Question

Time period of a simple pendulum is measured at Karachi. What change will occur in the time period, if it is measured on mount everest, explain?

Answer 1

The period of a pendulum is given by
`T=2 \pi \sqrt{ (l)/(g) }`
since Karachi is near sea level, g is larger than it is on Mt. Everest. That means the pendulum will have a larger period on Mt. Everest than it would in Karachi.
