Question
A simple pendulum of length has a bob of mass with a charge on it. A vertical sheet of change, with surface charge density passes through the point of suspension. At equilibrium, the spring makes an angle 
with the vertical. Its time period of oscillations is T in this position. Then
The correct answer is:
Electric intensity at due to sheet of charge,
force on the bob due to sheet of charge
As the bob is in equilibrium, so
