A particle at the end of a spring executes simple harmonic motion with a period t1 ,while the corresponding period for another spring is t2.If the period of oscillation with the two
springs in series is T, then :
detailed solution
Correct option is B
t1=2πMk1,t2=2πmk2 and T=2πMkeffWhen springs are connected in series, 1keff=1k1+1k2⇒T2=t12+t22Talk to our academic expert!
