The length of a simple pendulum is increased by 44%. The percentage increase in its time period will be

A

0.44

B

`sqrt(44) %`

C

0.2

D

0.1

Text Solution

Verified by Experts

The correct Answer is:
C
`(T_(2))/(T_(1))=sqrt(1.44)=(T_(2))/(T_(1))=1.20`
`(T_(2)-T_(1))/(T_(1))=0.20 therefore (T_(2)-T_(1))/(T_(1))%=20%`
