Assertion : Bob is released from rest position A. Given `theta_(0)` very small. Angular velocity of bob about point O is maximum and `(sqrt((g)/(l)))theta_(0)` at point O.

Reason : For small angular amplitudes , motion of bob is simple harmonic

A

If both Assertion and Reason are correct and Reason is the correct explanation of Assertion.

B

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

C

If Assertion is true but Reason is false.

D

If Assertion is false but Reason is true.

Text Solution

Verified by Experts

The correct Answer is:
B

(b) Maximum angular velocity `=omegatheta_(0)`
`=(2pif)theta_(0)=(2pi)((1)/(2pi)sqrt((g)/(l)))theta_(0)`
`=(sqrt((g)/(l)))theta_(0)`
