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\[{{90}^{o}}\], 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.
