Those who are looking for an answer to the question «Why is the electric field zero in a sphere?» often ask the following questions:

### 👉 Is electric field zero inside a sphere?

It isn’t necessarily zero. You are probably talking about a uniformly charged sphere with no other external electric fields. In this case, yes, the electric field at the center is zero. If the sphere had a nonuniform charge and/or there was another external electric field, the field at the center would not be zero.

### 👉 Why electric field inside a sphere is zero?

Why is electric field zero inside a hollow sphere? Hi, According to Gaussian’s law the electric field inside a charged hollow sphere is Zero. This is because the charges resides on the surface of a charged sphere and not inside it and thus the charge enclosed by the guassian surface is Zero and hence the electric field is also Zero.

### 👉 Why is electric field inside a sphere zero?

electric field in and out of the spherical shell. Why the field inside the conducting spherical shell is zero? Professor Lewin said and I quote," there is NO charge inside the conductor because any charge inside the conductor would make the electrons experience a force , the electrons will start to flow and they will kill the electric field."

If you have a conducting hollow sphere with a uniform charge on its surface, then will the electric field at every point inside the shell be 0. The reason the electric field is 0 at the center is clear from the symmetry of the sphere, but for a point at a certain distance from the center, shouldn't a net electric field exist?

That is correct if the charged sphere is a conductor in which charges are free to move. However, the electric field is also zero inside the cavity of a uniformly-charged spherical dielectric shell in which the charges are not free to move. May 4, 2017 #7

The electric field will be zero inside a spherical shell no matter if it is conducting or nonconducting, because according to Gauss’s law Φ=Qencϵ, where Φ is the electric flux thru the Gaussian surface, and Qenc is the charge inside the Gaussian surface.

The electric field immediately above the surface of a conductor is directed normal to that surface. Now, the gaussian surface encloses no charge, since all of the charge lies on the shell, so it follows from Gauss' law, and symmetry, that the electric field inside the shell is zero. Likewise, what is the charge of a sphere?

Now, for this configuration, the vector sum of all electric fields of all charges in the centre of said sphere would be exactly zero, quite straightforward so far, but how about any point in there other than the centre? I have seen a couple of proofs on how, the closer a point is to the surface of the conductor from the inside of course, the larger the electric field it experiences from its ...

### For a gauss's sphere where is the electric field zero?

Gauss's Law tells us that: ∬ E → (r →). d A → = ∑ q ϵ Now my teacher and others taught me that in order to find the electric field one can draw a gaussian surface and apply this law and would get that the electric field is equal to zero because the charge enclosed is 0.

### Why is the electric field inside a charged sphere zero?

This implies that the electric field inside a sphere is zero. Say you now add an electron inside the shell. The electrons on the surface will experience a force. This will cause them to move on the surface such that the net force\field becomes zero again.

### Why is the electric field inside a hollow sphere zero?

From Gauss law, the electric field is zero inside the hollow conducting sphere. So, the electric field inside any hollow conducting surface is zero provided that there are no charges enclosed by that region. In electrostatics free charges in a good conductor reside only on the surface. So the free charge inside the conductor is zero.

### Why is the electric field inside a metal sphere zero?

Since (1) the metallic sphere is an equipotential surface and (2) the potential inside the sphere must satisfy Laplace's equation, it follows, by the uniqueness theorem, that the potential inside the sphere is constant and thus, that the electric field inside the sphere is zero.

### When electric field zero?

Gauss law states that the total electric flux through a hypothetical closed surface is always equal to (1/ε0) times the net charge enclosed by the surface. The electric flux is nothing but the rate of flow electric field through the given area. Since the electric charges are not present inside the conductors, the electric field will remain zero.

### Does zero electric flux imply zero electric field?

No. Flux is only the electric field component normal to some surface. Zero flux might just mean the electric field is parallel to the surface.

### Zero electric potential but non-zero electric field?

Hence the physical significance of a point where the electric field is non-zero, is that the electric field is non-zero, and that the potential is zero there has no physical significance, because the point-values of the potential are not unique.

### Is electric field a sphere constant?

R = Radius of our sphere A = Surface area of our sphere = E = Electric Field due to a point charge = ε = permittivity of free space (constant)

### Why is the electric field strength zero inside a conducting or insulating sphere ?

Maybe you forget the word “hollow “ before sphere, cause in a solid insulating sphere the charge don’t need to move to surface, there is non zero field inside because …

### When is electric potential zero inside a sphere?

The electric field inside a conducting sphere is zero, so the potential remains constant at the value it reaches at the surface: Potentials for other charge geometries

### The electric field inside a hollow uniformly charged sphere is zero does this imply that the potential is zero inside the sphere explain?

Electric filed between two points inside the hollow sphere is zero means that the two points are at the same potential. In other words the potential difference between the two points is zero. It is not necessary that the potentials are zero.There fore The electric field inside a hollow uniformly charged sphere is zero implies the potentials at any two points inside the sphere are the same.

### Electric potential is zero but non zero electric field?

Hence the physical significance of a point where the electric field is non-zero, is that the electric field is non-zero, and that the potential is zero there has no physical significance, because the point-values of the potential are not unique.

### Is electric potential zero when electric field is zero?

Yes, electric potential can be zero at a point even when the electric field is not zero at that point. Considering the case of the electric dipole will help us understand this concept.

### Why is electric field inside a cavity of a non-conducting sphere not zero?

Consider a charged non conducting solid sphere of uniform charge density, and it as hole of some radius at the centre. Now suppose I apply Gauss law. As there is no charge inside the cavity, no charge is enclosed by Gaussian sphere, so electric flux is zero, hence electric field is zero. But this is not true according to sources like this, textbook ...

### Net electric field is zero?

Where is the net electric field zero? In Region II, between the charges, both vectors point in the same direction so there is no possibility of cancelling out. In Region III, the fields again point in opposite directions and there is a point where their magnitudes are the same. It is at this point where the net electric field is zero.
