Question

A given charge is situated at a certain distance from an electric dipole in the end-on position experiences a force `F` If the distance of the charge is doubled, the force acting on the charge will be
A. `2F`
B. `F//2`
C. `F//4`
D. `F//8`

Answer 1

Correct Answer - d
Force on charge `F=q(E_(a))=qxx(k.2p)/(r^(3))rArr F prop (1)/(r^(3))`
When `r rarr` doubled,. `F rarr 1/8` times
