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 $ \tau =pE\sin \theta $ on decreasing the distance between the two charges, and on decreasing angle $ \theta $ between the dipole and electric field, $ \sin \theta $ decreases therefore torque decreases.
