When a body of mass 2.0 kg is suspended by a spring, the spring is stretched. If the body is pulled down slightly and released, it oscillated up and down. What force is applied on the body by the spring when it passes through the mean position ? `(g=9.8Nkg^(-1))`

A spring has a natural length of 50 cm and a force constant of 2.0 xx 10^(3) N m^(-1) . A body of mass 10 kg is suspended from it and the spring is stretched. If the body is pulled down to a length of 58 cm and released, it executes simple harmonic motion. The net force on the body when it is at its lowermost position of its oscillation is (10x) newton. Find value of x. (Take g=10m/ s^(2) )

Certain weight is attached with a spring. It is pulled down and then released. It oscillates up and down. Its K.E. will be

When a mass m is hung on a spring, the spring stretched by 6 cm. If the loaded spring is pulled downward a little and released, then the period of vibration of the system will be

A body of mass m is suspended from three springs as shown in figure. If mass m is displaced slightly then time period of oscillation is

A body of mass 5 kg is suspended by a spring balance on an inclined plane as shown in figure. The spring balance measure

A mass of 1kg is hanged through a spring. The spring is stretched through 1cm. What is the energy stared in spring?

A body of mass 50 kg is suspended using a spring balance inside a lift at rest. If the lift startts falling freely, the reading of the spring balance is

When a body of mass M is hung from a spring, the spring extends by 1 em. If the body of mass 2M be hung from the same spring, the extension of spring will be
