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

Options

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.

Answer

B

Explanation

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