Explanation:
Given that,
Initial length of simple pendulum,
Initial time period,
We need to find the length of the simple pendulum when the period is exactly 1 second.
We know that the time period of simple pendulum is given by :
Put all values and find L₂
So, the length of the pendulum with a period of exactly one second is 25 cm.
