A mass M is suspended from a spring of negligible mass. The spring is pulled a little and then released so that the mass executes simple harmonic motion with time period T. If the mass is increased to ′ m ′ then the time period becomes ( 4/5T ) . The ratio of M/m ​is

its velocity is 0.4 ms^−1. The amplitude is This time period of a particle undergoing SHM is 16 s. It starts motion from the mean position. After 2 s
