Question

The time period of a simple pendulum depends on : (1) Length of pendulum (2) Amplitude of oscillation (3) Mass of bob (4) All of the above

Answer

Length of pendulum

Reason — The period of oscillation is directly proportional to the square root of its effective length i.e. T∝ √l or in other words, the square of the period of oscillation (T²) is directly proportional to its effective length (l) i.e., T² ∝ l. Hence, we can say that the period of a simple pendulum depends on the length of the pendulum.
