A pendulum attached with a string of length 2 m is released from one of its extreme
position at an angle of 30º from the vertical. What will be its velocity when it passes the mean
position? Take 'g' as 10 m/s2

It is this tangential component of gravity which acts as the restoring force. As the pendulum bob moves to the right of the equilibrium position, this force component is directed opposite its motion back towards the equilibrium position.
