Finding the time period of a Pendulum in an Electric Field

Description Image

I want to find the general expression for the time period of the pendulum, as required in question 20 of the attached picture. Question 19 contains additional information related to question 20.

I assume you have done the FBD, now u know the the forces acting on the ball. as the string is not stretchable and cannot get slack, the small displacement has to be made perpendicular to the string. it doesn't matter which side the displacement is made. u calculate the restoring force. from that you will get the expression for the angular frequency, thus the time period

Thank you sir, I was able to derive the required expression.
