Homework Statement
I have a conceptual question.
If there are two parallel infinite planes with charge densities of -sigma and +sigma, would the E field between them really be constant?
Homework Equations
E=sigma/(2*epsilon_0)
(K*q_0*Q)/r^2
The Attempt at a Solution
There is an example in my book that asks for the E field in between the two planes, and it is solved under the assumption that the E field remains the same regardless of the distance from either plane as long as it is within the two planes.
Is this done for simplicity or is it done that way because that is how it is in reality?
Because when I look at it I think of the electric field and electric force as varying with r.
