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?

Two blocks of masses m_1 and m_2 are attached to the lower end of a light vertical spring of force constant k. The upper end of the spring is fixed. When the system is in equilibrium, the lower block (m_2) drops off. The other block (m_1) will

A light pulley is suspended at the lower end of a spring of constant k_(1) , as shown in figure. An inextensible string passes over the pulley. At one end of string a mass m is suspended, the other end of the string is attached to another spring of constant k_(2) . The other ends of both the springs are attached to rigid supports, as shown. Neglecting masses of springs and any friction, find the time period of small oscillations of mass m about equilibrium position.

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 block weighing 10N is attached to the lower end of a vertical spring (k =200N/m), the other end of which is attached to a ceiling. The block oscillates vertically and has a kinetic energy of 2.0J as it passes through the point at which the spring is unstretched. The amplitude of the oscillation of block is

When a 20 g mass hangs attached to one end of a light spring of length 10 cm, the spring stretches by 2 cm. The mass is pulled down until the total length of the spring is 14 cm. The elastic energy, (in Joule) stored in the spring is :
