Question
Two identical plates A and B of parallel plate capacitor are given charge +q and -3q. If σ1 and σ2 are the charge densities on outer and inner faces of plate A then,
Options
A.σ1 = σ2
B.σ1 = 
C.σ1 = 
D.σ1 = 
Solution
Ep = 0
Q + Q - 3q = Q + q - Q
Q = 2q
σ1 =
σ2 =
= - 2σ1Create a free account to view solution
