Question

What happens to the time period of a simple pendulum when it is taken from equator to the pole?

Answer 1

Time period of a simple pendulum is given  :

Twhere, L  is effective length of the pendulum and g is the acceleration due to gravity.

As value of acceleration due to gravity increase as we go from equator to pole.
Since, T is inversely proportional to g, hence when the simple pendulum is taken from equator to poles, hence time period of the pendulum will decrease.
