Answer 2

Explanation:

simple pendulum consists of massless and inelastic thread whose one end is fixed to a rigid support and a small bob of mass m is suspended from the other end of the thread. Let I be the length of the pendulum. When the bob is slightly displaced and released, it oscillates about its equilibrium position.
