A block of mass ma is suspended vertically with a spring of spring constant k. The block is made to oscillate in a gravitation field. Its time period is fould to be T. Now the space between the plates is made gravity free, and an electric field E is produced in the downward direction. Now the block is given a charge q. the new time period of oscillation is

A block of mass m hangs from a vertical spring of spring constant k. If it is displaced from its equilibrium position, find the time period of oscillations.

The period of oscillation of a mass M suspended from a spring of spring constant K is T. the time period of oscillation of combined blocks is

A mass suspended from a spring of spring constant k is made to oscillate with a time period T. Now, the spring is cut into three equal parts and the mass is suspended from one of the parts. What will be the new time period of oscillations?

A block of mass m is connected to three springs as shown in Fig. The block is displaced down slightly and left free, it starts oscillating. Find time period of oscillations.

Two blocks rest on a smooth horizontal surface. They are connected by a spring of force constant k. If the system is set into oscillation find its time period.

A block of mass m is connected to a spring (spring constant k ). Initially the block is at rest and the spring is in its natural length. Now the system is released in gravitational field and a variable force F is applied on the upper end of the spring such that the downward acceleration of the block is given as a=g-alphat , where t is time elapses and alpha=1m//s^(2) , the velocity of the point of application of the force is:

Two identical springs of spring constant k are attached to a block of mass m and to fixed supports as shown in the figure. The time period of oscillation is

A block of mass m is suspended by different springs of force constant shown in figure. Let time period of oscillation in these four positions be T_(1),T_(2),T_(3) "and" T4 Then -
