Question
A simple pendulum moves from one end to the other in ¼ second. What is its frequency?
✓

Answer

Time taken by simple pendulum to move from one end to the other is $\frac{ T }{2}$ second.
Given: $\frac{ T }{2}=\frac{1}{4}$ second
$\therefore T =\frac{1}{2}$ second
$\therefore$ Frequency, $n =\frac{1}{ T }=2 Hz$
