Solution
Verified by Toppr
Correct option is C)

## The bob of pendulum executing   has maximum velocity at the mean position.Maximum velocity is given by             where   is the amplitude of oscillation and   is the angular frequency given by     For the same length of the string,   remains the same.Thus
