Consider two large ,identical parallel conducting plates having surface `X` and `Y` .facing each other.The charge per unit area on `X` is `sigma_(1)` and charge per unit surface area of `Y` is `sigma_(2)` .Then,

Options

A. `sigma_(1)=-sigma_(2)` in all cases
B. `sigma_(1)=-sigma_(2)` only if a charge is given to one plate only.
C. `sigma_(1)=sigma_(2)=0` if equal charges are given to both the plates.
D. `sigma_(1)gtsigma_(2)` if `X` is given more charge than `Y`.

Answer

A, C
