Question 343: Oscillations

Question

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

Accepted Answer

The periodic time of a pendulum is given by
$$\mathrm{T=2\pi\sqrt{\frac{l}{g}}}$$
$$	herefore T \propto \sqrt l$$
Hence, to increase the periodic time, length has to be increased. The periodic time is independent of mass and amplitude.

Answer

reduce the mass of the bob.

Answer

reduce the amplitude of oscillation.

Answer

increase the length of the pendulum.

Answer

reduce the length of the pendulum.
