Simple Pendulum

A simple pendulum is oscillating with a time period T. The bob is metallic and has a charge +q. Choose the correct statement(s)

1. T will increase if a uniform electric field is applied in vertically upward direction

2. T will increase if a negative charge is placed at the point of suspension

3. T will not change if a negative charge is placed at the point of suspension

4. T will decrease if a uniform electric field is applied in vertically downward direction
