Q. A simple pendulum is taken from the equator to the pole. Its period
A) Decreases
B) Increases
C) Remains the same
D) Decreases and then increases
Explanation
(a) As we go from equator to pole the value of $g$ increases. Therefore time period of simple pendulum decreases
$\left( \because T \propto \frac{1}{\sqrt{g}} \right)$
