The time period of a simple pendulum is 2 sec. If its length is increased 4 times, then its period becomes

Moderate

A

16 sec
B

12 sec
C

8 sec
D

4 sec

Solution

$T \propto \sqrt{l} \Rightarrow \frac{T_{1}}{T_{2}} = \sqrt{\frac{l_{1}}{l_{2}}} \Rightarrow \frac{2}{T_{2}} = \sqrt{\frac{l}{4 l}} \Rightarrow T_{2} = 4 \sec$
