Question

Two charges are at a distance ‘d’ apart. If a copper plate (conducting medium) of thickness $\frac{d}{2}$ is placed between them, the effective force will be

• A. 2F
• B. $\frac{F}{2}$
• C. \N
• D. $\sqrt{2}F$

Answer 1

The correct option is C \N

Effective air separation between them becomes infinite so force becomes zero.
