Electrostatics Question 320

Question: 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 [J & K CET 2005]

Options:

A) E

B) E / 4

C) E / 2

D) 2E

Show Answer

Answer:

Correct Answer: C

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.
