JEE Main level, single correct, medium

142 of 194

Question 142 of 194

A particle at the end of a spring executes simple harmonic motion with a period t1t_1, while the corresponding period for another spring is t2t_2. If the period of oscillation with the two springs in series is t\mathrm{t}, then

Show answer and solution

Answer: (B) ∝x2\propto \mathrm{x}^2

t12+t22=T2t_1^2+t_2^2=T^2
