A spring of spring constant k is stretched by distance r. Obtain formula for elastic potential energy of a stretched spring. Plot graph of energies versus distance.

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 elastic potential enegry of a stretched spring is given by E = 50 x^(2) . Where x is the displacement in meter and and E is in joule, then the force constant of the spring is

Two springs have force constants k_(A) and k_(B) such that k_(B)=2k_(A) . The four ends of the springs are stretched by the same force. If energy stored in spring A is E , then energy stored in spring B is.

The fig. shows an infinite tower of identical springs each having force constant k. The connecting bars and all springs are massless. All springs are relaxed and the bottom row of springs is fixed to horizontal ground. The free end of the top spring is pulled up with a constant force F. In equilibrium, find (a) The displacement of free end A of the top spring from relaxed position. (b) The displacement of the top bar B1 from the initial relaxed position.

An object with uniform density ρ is attached to a spring that is known to stretch linearly with applied force as shown below. When the spring-object system is immersed in a liquid of density rho_(1) as shown in the figure, the spring stretches by an amount x_(1)(rho gt rho_(1)) . When the experiment is repeated in a liquid of density rho_(2) gt rho_(1) , the spring stretches by an amount x_(2) . Neglecting any buoyant force on the spring, the density of the object is

A block is suspended by an ideal spring of force constant force F and if maximum displacement of block from its initial mean position of rest is x_(0) then
