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 $ \text{9}0{}^\circ $ 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 $ \text{9}0{}^\circ $ about it’s perpendicular axis then given point comes out to be on equator. So field will become E / 2 at the given point.
