Question

4 The pendulum bob in the fig hangs from a cord of length 40 cm. The pendulum bob is pulled about 10 em to the side (from the equilibrium positon) and gains a height of 1.3 em. The pendulum is released to swing and the sensor probe “RANGER", measures its horizontal velocity which varies with time as it swings. per an st A-The maximum kinetic Energy and the maximum potential energy of the pendulum occur at the highest point of the swing B- The minimum kinetic Energy and the minimum potential energy of the pendulum occur at the lowest point of the swing. C- The minimum kinetic Energy and the maximum potential energy of the pendulum occur at the lowest point of the swing. D- The maximum kinetic Energy and the minimum potential energy of the pendulum occur at the lowest point of the swing.

Explanation / Answer

The potential energy is maximum at maximum height that is at extream of the string.The kinetic energy is maximum at lowest point of the swing at this point potential energy is minimum.

option(D) is correct
