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

F propto (1/r3) (F'/F)=(r3/8 r3) F'=(F/8)

Q. 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 :-

$2 F$

$F /2$

$F /4$

$F /8$

$F \propto \frac{1}{r ^{3}}$
$\frac{F ^{^{'}}}{F} = \frac{r ^{3}}{8 r ^{3}}$
$F^{^{'}} = \frac{F}{8}$
