A) \[E\propto \frac{1}{{{r}^{2}}}\]
B) \[E\,\propto \frac{1}{{{r}^{3}}}\]
C) \[E\propto \,{{r}^{2}}\]
D) \[E\propto \,\frac{1}{{{r}^{4}}}\]
Correct Answer: B
Solution :
Intensity of electric field at axis line of dipole \[E=\frac{1}{4\pi {{\varepsilon }_{0}}}\frac{2p}{{{r}^{3}}}\] Or \[E\propto \frac{1}{{{r}^{3}}}\]You need to login to perform this action.
