If the length of the simple pendulum is ...

If the length of the simple pendulum is increased by 44% from its original length, calculate the percentage increase in time period of the pendulum.

Text Solution

Verified by Experts

Since ` T prop sqrtT , T = " constant " sqrtl`
`T_f/T_i = sqrt( (l + 44/100 l )/(l)) = sqrt(1.44) = 1.2`
` therefore T_f = 1.2 T_i = T_i + 20% T_i`
