Assertion: If bob of a simple pendulum is kept in a horizontal electric field, its period of oscillation will remain same.
Reason: If bob is charged and kept in horizontal electric field, then the time period will be decreased.

A

if both Assertion and Reason are true and the Reason is correct explanation of the Assertion.

B

If both Assertion and Reason are true but Reason is not the correct explanation of the Assertion.

C

if Assertion is true, but the Reason is false.

D

if both Assertion and Reason are false

Text Solution

Verified by Experts

The correct Answer is:
b
When the bob is placed in an electric field, the bob time period of simple pendulum having charged bob is placed in a horizontal electric field then the period will be decreased because there will be a increase the restoring force
