A body is suspended from the lower end of a vertical spring. What shall be the effect on the position of the body when a current is sent through the spring? Does it depend upon the direction of current in the spring?

If a current is passed through a spring then the spring will

A direct current is sent through a helical spring. The spring -

A light body is hanging at the lower end of a vertical spring . On passing current in the spring, the body

An object weights W newton on earth. It is suspended from the lower end of a spring balance whose upper end is fixed to the ceiling of a space capsule in a stable orbit around the earth. The reading of the spring balance will be

A body of mass 2 kg suspended through a vertical spring executes simple harmonic motionof period 4s. If the oscillations are stopped and the body hangs in equillibrium, find the potential energy stored in the spring.

A mass suspended on a vertical spring oscillates with a period of 0.5s . When the mass is allowed to hang at rest, the spring is stretched by

A ball of mass m is attached to the lower end of a light vertical spring of force constant K . The upper end of the spring is fixed. The ball is released from rest with the spring at its normal ( unstretched ) length, and comed to rest again after descending through a distance x .

A body of mass m is suspended from vertical spring and is set into simple harmonic oscillations of time period T. Next the spring is fixed at one end on a smooth horizontal table and same body is attached at the other end. The body is pulled slightly and then released to produce horizontal oscillations of the spring. The time period of horizontal oscillations is

A body of mass 'm' is suspended to an ideal spring of force constant 'k'. The expected change in the position of the body due to an additional force 'F' acting vertically downwards is

On compressing a spring by 0.5 m, a restoring force of 20 N is developed. When a body of mass 5 kg is placed on the spring, then calculate the (a) force constant of the spring. (b) the distance through which the spring is depressed under the weight of the body. (c ) the period of oscillation of the spring if the the body is pushed down and then released.
