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.

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 ...
