The electric field due to an electric dipole at a distance r from its centre in axial position is E. If the dipole is rotated through an angle of 90° about its perpendicular axis, the electric field at the same point will be
A
E
B
E / 4
C
E / 2
D
2E
Answer
E / 2
Explanation
Solution
When the dipole is rotated through at an angle of 90° about it's perpendicular axis then given point comes out to be on equator. So field will become E / 2 at the given point.
