Question

When a simple pendulum is taken from the Equator to the Pole, its period of oscillation will :

• A. increase
• B. decrease
• C. remains same
• D. can't say

Answer 1

The correct option is B decrease

Time period of simple pendulum is given by $T=2\pi \sqrt{\frac{l}{g}}$

where $l$ is the length of the pendulum and $g$ is the acceleration due to gravity.

We know that $g_{pole}>g_{equator}$

$⟹T_{pole}<T_{equator}$

Thus time period of simple pendulum decreases when it is taken from equator to pole.
