Q. A given charge situated at a certain distance from an electric dipole in the end on opposition, experiences a force F. If the distance of charge is doubled, the force acting on the charge will be
A) 2 F
B) F /2
C) F /4
D) F /8
Explanation
(d) In case of an electric dipole, $\ F \propto \frac{1}{r^{3}}\ $
$\therefore$ new force $= F/2^{3} = F/8.$
