A pendulum clock is running fast. To correct its time, we should

Options

  1. Areduced the mass of bob
  2. Breduce the amplitude of oscillation
  3. Cincrease the length of pendulum
  4. Dreduce the length of the pendulum

Correct answer

C. increase the length of pendulum

Step-by-step solution

The periodic time of a pendulum is given by aligned & T =2 g & T aligned Hence to increase the periodic time, length has to be increased. The periodic time is independent of mass and amplitude.
