pendulum above oscillates with a period of 2.0 seconds when it is displaced through a horizontal distance of 10.0 cm from the equilibrium position and released. Find: (1) the length of the pendulum;
(ii) the angle 8 through which it is displaced;
(ii) the gain in potential energy when the pendulum in position A and the mass of the bob
is 50 g. (g=10 m s²)
1. The length of the pendulum is 0.20 m.
2. The angle 8 through which it is displaced is 0.1745 radians.
3. The gain in potential energy when the pendulum is in position A is 0.25 J.
