MCQ

What effect occurs on the frequency of a pendulum if it is taken from the earth surface to deep into a mine

A
Increases
✓
Decreases
C
First increases then decrease
D
None of these

✓

Answer

Correct option: B.

Decreases

b
(b) In deep mine $g' = g\,\left( {1 - \frac{d}{R}} \right)$; i.e., $g$ decreases so according to $n \propto \sqrt g ,$ frequency also decreases.
