A neutral pendulum oscillates in a uniform electric field as shown in figure. If a positive charge is given to the pendulum, then its time period

A

will increase

B

will decrease

C

will remain constant

D

will first increase then decrease

Text Solution

Verified by Experts

The correct Answer is:
A
`g_e=g-((qE)/m)`
or `g_e` will decrease. Hence, `T=2pi sqrt (l/g_e)` will increase
