A) \[\frac{F}{2}\]
B) \[\frac{F}{4}\]
C) \[\frac{F}{6}\]
D) \[\frac{F}{8}\]
Correct Answer: D
Solution :
Force exerted by an electric dipole on a charge is inversely proportional to the cube of distance of the charge from the centre of the dipole \[F\propto \frac{1}{{{r}^{3}}}\] \[\therefore \] \[\frac{F}{F}={{\left( \frac{r}{r} \right)}^{3}}\] \[\frac{F}{F}={{\left( \frac{2}{1} \right)}^{3}}\] \[F=\frac{F}{8}\]You need to login to perform this action.
