Question

Two conducting plates A and B are placed parallel to each other at a small distance between them. Plate A is given a charge $q_1$ and plate B is given a charge $q_2$. Then,

• A. the outer surfaces of A and B (not facing each other) get no charge.
• B. the inner surfaces of A and B (facing each other) get all the charge
• C. the inner surfaces of A and B (facing each other) get equal and opposite charge of magnitude $\left|\frac{q_1-q_2}{2}\right|$
• D. the outer surfaces of A and B (not facing each other) get charge of the same polarity and of magnitude $\left|\frac{q_1+q_2}{2}\right|$

Answer 1

Answer: (C), (D)

The correct options are
C the inner surfaces of A and B (facing each other) get equal and opposite charge of magnitude $\left|\frac{q_1-q_2}{2}\right|$
D the outer surfaces of A and B (not facing each other) get charge of the same polarity and of magnitude $\left|\frac{q_1+q_2}{2}\right|$
