37) A pendulum whose period in a vacuum is 2.3 second is placedin a resistive medium. Its amplitude on each swing is observed tobe half that on the previous swing. What is its new period? Giventhat the pendulum bob is of mass 0.2 kg, and is subjected to aperiodic force of amplitude 0.5 N and period 1 s, find the angularamplitude of the resulting forced oscillation.
