Spring

There are two springs P and Q . Spring constant for P is K and that for Q is 3K . Both the springs are elongated by applying force of same magnitude . If U is energy stored in spring P then energy stores in spring Q is

The spring constant of spring A is twice the spring constant of spring B . Each of the spring is cut into two pieces. First piece of spring A is (4//5) of the total length. Second piece of spring B is (5//6) of its total length. Both springs are of equal lengh initially :

Two springs are in a series combination and are attached to a block of mass 'm' which is in equilibrium. The spring constants and extension in the springs are as shown in the figure. Then the force exerted by the spring on the block is :

Figure shows a force compression curve of a spring. A body of mass 5kg moving with the velocity of 8m//s hits the spring. Calculate the force constant of the spring and also the compression produced in the spring when the body hits it.

Two equal masses are attached to the two ends of a spring of spring constant k. The masses are pulled out symmetrically to stretch the spring by a length x over its natural length. The work done by the spring on each mass is
