The length of a simple pendulum is 0.79m and the mass of the particle (the ''bob'') at the end of the cable is 0.24kg. The pendulum is pulled away from its equilibrium position by an angle of `8.50^(@)` and released from rest. Assume that friction can be neglected and that the resulting oscillatory motion is simple harmonic motion. What is the angular frequency of the motion?

A

9.1 rad/s

B

12 rad/s

C

8.2 rad/s

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^(@) with the vertical and let go. The kinetic energy of the bob while crossing its equilibrium position will be

The bob of a simple pendulum is displaced from its equilibrium position 'O' to a position 'Q' which is at a height 'h' above 'O' and the bob is then released. Assuming the mass of the bob to be 'm' and time period of oscillation to be 2.0s , the tension in the string when the bob passes through 'O' is
