Question

If the amplitude of oscillation made two times, how will be the period affected ?

Answer 1

1. Since, the time period of a pendulum$T=2\pi \sqrt{\frac{l}{g}}$
2. Where, l is the length of a pendulum and, g is acceleration due to gravity.
3. The time period does not depend upon the amplitude of oscillation.
4. Hence, the time period of oscillation is not affected if the amplitude made two times.
