Question

Consider two large ,identical paralllel conducting plates having surface `X` and `Y` .facing eacg other.The charge per unit area on `X` is `sigma_(1)` and charge perunit surface area of `Y` is `simga_(2)` .Then,
A. `sigma_(1)=-sigma_(2)` only if a charge is given to either `X` or `Y`.
B. `sigma_(1)=sigma_(2)=0` if equal charges are given to both `X` and `Y`.
C. `sigma_(1) gt sigma_(2)` if `X` is given a charge more than that given by `Y`
D. `sigma_(1)=-sigma_(2)` in all cases.

Answer 1

Correct Answer - A,C
Use `E=(sigma)/(epsilon_(0))` between the plates.
