Question

Two large conducting plates are placed parallel to each other maintaining very small separation between them. It charges of equal magnitude but opposite signs are given to them, then the charge appearing on the outer faces of the conductors will be?

• A. Unequal
• B. Zero
• C. Can't say

Answer 1

The correct option is B Zero

Let's assume that +Q amount of charge is given to one conducting plate and -Q to the other.
Now charge on the outer faces of the two conductors will be $=\frac{\sum Q}{2}=\frac{Q-Q}{2}=0$

Hence, all the charge will reside on the inner faces of both the conductors.
