Q. The mass of a simple pendulum bob is $100\, gm$. The length of the pendulum is $1 m $ The bob is drawn aside from the equilibrium position so that the string makes an angle of $60^{\circ}$ with the vertical and let go. The kinetic energy of the bob while crossing its equilibrium position will be
