An object of mass 0.2 kg executes simple harmonic along X-axis with frequency of 25/π Hz. At the position X = 0.04 m, the object has kinetic energy of 0.5 J and potential energy of 0.4 J. Amplitude of oscillation in meter is equal to

Time period of a block suspended from the upper plate of a parallel plate capacitor by a spring of stiffness k is T. When block is uncharged. If a charge q is given to the block then, the new time period of oscillation will be

A man weighing 60 kg stands on the horizontal platform of a spring balance. The platform starts executing simple harmonic motion of amplitude 0.1 m and frequency 2/π Hz. Which of the following statements is correct

A man having a wrist watch and a pendulum clock rises on a TV tower. The wrist watch and pendulum clock by chance fall from the top of the tower. Then

A force of 6.4 N stretches a vertical spring by 0.1 m. The mass that must be suspended from the spring so that it oscillates with a period of π/4 s. is

Four massless springs whose force constants are 2k, 2k, k and 2k respectively are attached to a mass M M kept on a frictionless plane (as shown in figure). If the mass M is displaced in the horizontal direction, then the frequency of oscillation of the system is

Values of the acceleration A of a particle moving in simple harmonic motion as a function of its displacement x are given in the table below
The period of the motion is

Two pendulums have time periods T and 5T/4 . They start S.H.M. at the same time from the mean position. What will be the phase difference between them after the bigger pendulum has completed one oscillation

The periodic time of a particle doing simple harmonic motion is 4 second. The time taken by it to go from its mean position to half the maximum displacement (amplitude) is
