KPSC KAS 2017 · Question 136 of 200

The pendulum of a clock consists of a heavy point mass (bob) tied to a massless string. It is oscillating faster and so the clock is going fast. What option below should be chosen in order to reduce the time of oscillation ?

General Science

Answer: B. The length of the pendulum should be increased

A pendulum's period T = 2π√(l/g) is independent of the bob's mass; a fast clock is slowed by increasing the pendulum's length.
