1.	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.
Answer» Solution :Since `Tpropsqrt(L)` Therefore, T = constant `sqrt(l)` `(T_(f))/(T_(i))=sqrt((l+(44)/(100)l)/(l))=sqrt(1.44)=1.2` Therefore, `T_(f)=1.2T_(i)=T_(i)+20%T_(i)`
