Question:medium

A simple pendulum is taken at a place where its distance from the Earth's surface is equal to the radius of the Earth. Calculate the time period of small oscillations if the length of the string is 4.0 m. (Take \( g = 9 \, \text{m/s}^2 \) at the surface of the Earth.)

Show Hint

When the pendulum is at a height equal to the Earth's radius, the effective gravity is reduced, which increases the time period of oscillation.
