# Homework Help: Is the force experienced by a charge at any point between two charged parallel plates

Hello,

Is the force experienced by a charge at any point between two charged parallel plates the same?

Just a preliminary step to my homework question,
Let's say I have two parallel charged plates. (positive on top and negative on bottom with field lines going downwards.).

Would all positive and negative charges experience the same force at any point between the plates?

cheers.

Re: Is the force experienced by a charge at any point between two charged parallel pl

When the dimensions of the charged plates are large compared to the distance between the plates then the electric field E that exists between the plates is essentially uniform and of constant value.

The force experienced by some charge q between the plates is then given by q*E. So the magnitude of the force will be proportional to the magnitude of the charge and magnitude of the field, and the direction of the force depends upon the sign of the charge and the direction of the field.
