Questions
Calculate the change in the length of a simple pendulum of length 1m, when its period of oscillation changes from 2 sec to 1.5 sec
detailed solution
Correct option is A
Time period =T=2πlg where l= length of pendulum g=acceleration due to gravity T α l T1T2=l1l2 by question T1=2,T2=1.5 21.5=l1l2,squaring on both sides ⇒l2=916 ⇒Δl=l2−l1 Δl=916−1 change in length=Δl=−716Talk to our academic expert!
