The length of a seconds pendulum if it is placed at height

2 R

(

R

: radius of earth) is

\frac{10}{x \pi^2}

metres. Find

x

View answer and explanation

Correct option: A

Option A (9) is correct because the length of the pendulum is calculated using the formula for the time period of a simple pendulum, considering the change in gravity at a height of 2R.
