A) \[\frac{1}{r}\]
B) \[\frac{1}{{{r}^{3}}}\]
C) \[\frac{1}{{{r}^{4}}}\]
D) \[\frac{1}{{{r}^{2}}}\]
Correct Answer: D
Solution :
(d) \[\frac{1}{{{r}^{2}}}\] The potential of electric dipole at a distance r from the centre of the dipole is \[V=\frac{1}{4\pi {{\varepsilon }_{0}}}\frac{p\,\cos \theta }{{{r}^{2}}}\] \[V\propto \frac{1}{{{r}^{2}}}\]You need to login to perform this action.
