Question and Answer

Two bodies (M) and (N) of equal masses are suspended from two separate massless springs of spring constants (k_1) and (k_2) respectively. If the two bodies oscillate vertically such that their maximum velocities are equal, the ratio of the amplitude of vibration of (M) to the of (N) is.
(A) \(\frac{{k}_{{{1}}}}{{k}_{{{2}}}}\)
(B) \(\sqrt{{\frac{{k}_{{{1}}}}{{k}_{{{2}}}}}}\)
(C) \(\frac{{k}_{{{2}}}}{{k}_{{{1}}}}\)
(D) \(\sqrt{{\frac{{k}_{{{2}}}}{{k}_{{{1}}}}}}\)
