A simple pendulum with a negatively charged bob is made to oscillate just above a positively charged plate. What happens to its time period?

Text Solution

Verified by Experts

Due to electrostatic attraction between the bob and the plate, the bob feels greater! force in the vertically down ward direction. This virtually increases g, and hence time period decreases.
