A) E
B) \[\frac{E}{4}\]
C) \[\frac{E}{2}\]
D) 2E
Correct Answer: C
Solution :
When a dipole AB of very small length is taken. then for a point P located at a distance r from the axis the electric field is given by \[E=\frac{1}{4\pi {{\varepsilon }_{0}}}\frac{2P}{{{r}^{3}}}\] ?(i) When dipole is rotated by \[\text{9}{{\text{0}}^{\text{o}}}\text{,}\]then electric field is given by \[E=\frac{1}{4\pi {{\varepsilon }_{0}}}\frac{P}{{{r}^{3}}}\] ?(ii) From Eqs. (i) and (ii), we get \[\]You need to login to perform this action.
