A) \[E\propto \frac{1}{{{r}^{4}}}\]
B) \[E\propto \frac{1}{{{r}^{3}}}\]
C) \[E\propto \frac{1}{{{r}^{2}}}\]
D) \[E\propto \frac{1}{r}\]
Correct Answer: B
Solution :
Here: Electric field\[=E\] Distance \[=r\] The electric field intensity due to dipole is \[E=\frac{1}{4\pi {{\varepsilon }_{0}}}\times \frac{2p}{{{r}^{3}}}\propto \frac{1}{{{r}^{3}}}\]
