detailed solution
Correct option is C
time period of a simple pendulum is T=2πlg here 2π, g are constant Tαl on squaring, kT2=l-----(1) kT12=l+20---(2) kT22=l-20---(3) add equation (2)and (3) k(T12+T22)=2l---(4) substitute l from equation (1) k(T12+T22)=2(kT2) T12+T22=2T2Talk to our academic expert!
