Questions
Two pendulums of lengths 1.44 and 1 metre length start swinging together. After how many vibrations of the longer pendulum will they again start swinging together ?
detailed solution
Correct option is C
Ti=2π1.44g&T2=2π1gLet shorter pendulum make n vibrations. Then longer will make one less than n to come in phase again i.e. nt2=2(n−1)t1 n×1=(n−1)1210n =6 n'=n−1=6−1=5Talk to our academic expert!
