Electrostatics Question 707

Question: On decreasing the distance between the two charges of a dipole which is perpendicular to electric field and decreasing the angle between the dipole and electric field, the torque on the dipole

Options:

A) increases

B) decreases

C) remains same

D) cannot be predicated

Show Answer

Answer:

Correct Answer: B

Solution:

[b] Since τ=pEsinθ on decreasing the distance between the two charges, and on decreasing angle θ between the dipole and electric field, sinθ decreases therefore torque decreases.
