What will be the value of the time period of a simple pendulum if the amplitude is reduced to half of its original value?

Answer»

Formula for the time period of a simple pendulum,

\(T = 2 \pi \sqrt{\frac{l}{g}}\)

In this expression, there is no term ‘a’, hence the time period is independent of the amplitude of oscillation. Thus, the time period remains unaffected.
