Two charges are at a distance `d` apart. If a copper plate (conducting medium) of thickness `d//2` is placed between them , the effictive force will be

A

`F//2`

B

zero

C

2F

D

`sqrt(2) F`

Text Solution

Verified by Experts

The correct Answer is:
B

The dielectric constant for metal is infinity, the force between the two charges would be reduced to zero .
