The bob of simple pendulum of length 'L' is released from a position of small angular displacement . Its linear displacement at time 't' is (g = acceleration due to gravity)

Answer: (A)

Solution

For small angles the pendulum executes S.H.M. with angular frequency and amplitude (linear) . Released from the extreme position at , the displacement is maximum at , so it follows a cosine law: ,
