A simple pendulum has time period `T` The bob is given negative charge and surface below it is given position change new time period will be

A

less then `T`

B

greater then `T`

C

equal to `T`

D

infinite

Text Solution

Verified by Experts

The correct Answer is:
A
In this casetime period of pendulum becomes
`T = 2 pi sqrt((1)/((g + (qE)/(m)))`
`rArr T lt T`
