Those who are looking for an answer to the question «Why is the dipole plate electric field non uniform?» often ask the following questions:

👉 Why is the dipole plate electric field not uniform?

An electric dipole always experiences a torque when placed in uniform as well as non-uniform electric field. But in non-uniform electric field, dipole will also experience net force of attraction. So the electric dipole in non-uniform electric field experiences both torque and force.

👉 Is electric field uniform in dipole?

Consider an electric dipole in a uniform electric field which is due to some other source.The dipole moment ( ) makes an angle θ with the electric field () as shown in Figure. The forces on charges +q and -q are qE and -qE respectively. Note:The net force on a dipole in a uniform electric field is zero.

👉 Dipole kept in uniform electric field will?

In a uniform electric field, both the point charges comprising the dipole will experience force, equal in magnitude and opposite in direction. Though the net force will always be zero, the torque will be in same direction for both the charges. Hence torque will not be zero.

The premise of your question is faulty in that when a dipole is placed in a non-uniform electric field, the direction of the net force experienced by it is not always along the direction of increasing electric field. (I will work with the assumption that you don't speak of a case in which the dipole is titled with respect to the electric field) Two cases exist--the dipole is either parallel or ...

If a dipole placed in non-uniform electric field, it will experience net force of attraction per meter towards electric field of large magnitude that is, F(net)=p(E2-E1).

The magnitude of charges of electric dipole is 3. 2 × 1 0 − 5 and distance between them is 2. 4 A. If it is placed in an electric field 4 × 1 0 5 V / m then its diple moment is (in C-m) Hard

It's Griffiths, in a footnote on page 165. I will quote it: 'In the present context Eq. 4.5 could be written more conveniently as F=∇(p.E).However it is safer to stick with (p.∇)E because we will be applying the formula to materials in which the dipole moment (per unit volume) is itself a function of position and this second expression would imply (incorrectly) that p too is to be ...

This is because the electric field is uniform between the plates. In more general situations, regardless of whether the electric field is uniform, it points in the direction of decreasing potential, because the force on a positive charge is in the direction of E and also in the direction of lower potential V .

As we know that, when a dipole is placed in a uniform electric field, both the charges as a whole do not experience any force, but it experiences a torque equal to τ which can be given as, This torque rotates the dipole unless it is placed parallel or anti-parallel to the field.

charge to the positive charge. This implies that the electric dipole moment vector points from the negative charge to the positive charge. Note that the electric field lines run away from the positive charge and toward the negative charge. There is no inconsistency here, because the electric dipole moment has to do with the positions of the charges, not the field lines.

This is because the parallel plates do not extend out to infinity in each direction. Because it is a conducting plate the charges will build up on the surface. Therefore there will be a charge on the front of the plate, as well as on the back of the plate. This happens on both plates for both charges.

Further, since the electric field stays non-uniform, the pieces of paper get attracted in the direction of the comb. Question: An electric dipole is placed at an angle of 30 o with an electric field of intensity 2 × 10 5 N/ C. It experiences a torque of 4 N m. Calculate the charge on the dipole if the dipole length is 2 c m. 4; 2; 8; 1

To show that the vector of electric intensity changes direction in the centre of the plate, the electric intensity reaches negative values after crossing the centre of the plate. The electric field is uniform outside the plate with intensity \(E\,=\, \frac{\varrho a}{2 \varepsilon_0}\).

What happens when a dipole is placed in non uniform electric field?

If an electric dipole is placed in a nonuniform electric field, then the positive and the negative charges of the dipole will experience a net force. And as one end of the dipole is experiencing a force in one direction and the other end in the opposite direction, so the dipole will have a net torque also.
