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

Options

  1. Areduce the amplitude of oscillation.
  2. Bincrease the length of the pendulum.
  3. Creduce the length of the pendulum.
  4. Dreduce the mass of the bob.

Correct answer

C. reduce the length of the pendulum.

Step-by-step solution

The period of a simple pendulum is given by aligned & T=2 L g & T L aligned If the clock is running slow, that means time period is larger as compared to the correct value. So, by reducing the length of the pendulum the time period can be shortened to get the correct value.
