The Coulomb force of attraction between ...

The Coulomb force of attraction between two charges separated by a distance is 4N. If a dielectric medium of dielectric constant 2 is kept to fill the space between them, the force of attraction now becomes

A

8N

B

4N

C

6N

D

2N

Text Solution

Verified by Experts

The correct Answer is:
D
Given, force between two charges situated in vacuum,
F=4N
According to question, a dielectric medium of dielectric constant 2 is kept to fill the space between them, then force of attraction now becomes
`F.=(F)/(2)=(4)/(2)=2N`
