In the case of sustained force oscillations the amplitude of oscillations

In the case of resonance, in forced oscillations

A mass is suspended from the end of a spring. When the system is oscillating the amplitude of oscillation is 4 cm and maximum kinetic energy of oscillation of the system is 1J. Then the force constant of the spring is

At resonance, the amplitude of forced oscillations is

At resonance, the amplitude of forced oscillations is

In the previous question, the amplitude of the oscillation is

For SHM to take place force acting on the body should be proportional to -x or F =- kx . If A be the amplitude then energy of oscillation is 1//2KA^(2) . The amplitude of oscillation is
