A) \[E\propto \frac{1}{r}\]
B) \[E\propto \frac{1}{{{r}^{2}}}\]
C) \[E\propto \frac{1}{{{r}^{3}}}\]
D) \[E\propto \frac{1}{{{r}^{4}}}\]
Correct Answer: C
Solution :
The electric field strength due to a dipole at any general point P (r, \[\]) is \[E=\frac{1}{4\pi {{\varepsilon }_{0}}}\frac{p}{{{r}^{3}}}\sqrt{(1+3{{\cos }^{2}})}\propto \frac{1}{{{r}^{3}}}\]You need to login to perform this action.
