In a simple pendulum, the period of oscillation $T$ is related to length of the pendulum $l$ as

A

$\frac{l}{T} = $constant

B

$\frac{{{l^2}}}{T} = $ constant

C

$\frac{l}{{{T^2}}} = $ constant

D

$\frac{{{l^2}}}{{{T^2}}} = $ constant

Solution

(c) $T = 2\pi \sqrt {\frac{l}{g}} $

$\Rightarrow \frac{l}{{{T^2}}} = \frac{g}{{4{\pi ^2}}} = $ constant
