Question

The period of a simple pendulum X is 5s. What is the period of a simple pendulum Y which makes 50 vibrations in the same time it takes X to make 20 vibrations?

Options

A) 12.5s

B) 2.5s

C) 2.0s

D) 1.2s

The correct answer is A.

Explanation:

\(T_x = \frac{20}{5} = 4s\)

\(T_y = \frac{50}{4} = 12.5s\)
