what is the work done in taking a charge from one point to another between the plates of a capacitor?
The electric field due to a charged sheet at a particular point(σ/2ε0) does not depend upon the distance between the plate and the point. D
oes it mean that the plate exerts equal force on a charge at any given distance from the plate (even infinity)?!!! i am so confused.. can someone help me?!

1It is generally assumed that there is no fringing in the electric field as long as it is within the plates. That is why we assume that the field is constant. But in reality it is not. But for your purpose you can take the field constant as long as you are inside the volume defined by the capacitor plates. Hope it solves your doubt.
