A spring, which is initially in its unstretched condition, is first stretched by a length x and then again by a further length x. The work done in the first case is `W_(1)` and in the second case is `W_(2)`.

A spring,which is initially is its unstretched condition,is first stretched by a length 5cm and then again by a further length 5cm.The work done in the first case is W_(1) , and in the second case is W_(2) .Then the work required to stetch it further by another 5 cm is ( K = 5xx10^(3) )

A spring which is initially in un-streatched condition, is first stretched by a length x and again by a further length x. The work done in the first case W_(1) is one third of the work done in second case W_(2) . True of false ?

An elastic spring of length L and spring constant K is stretched by a length x. It is then again stretched to a length y. The work done in the second case will be

A spring of force constant k is stretched by a small length x . Find the work done in stretching it further by a small length y .

A spring of force constant K is first stretched by distance a from its natural length and then further by distance b. The work done in stretching the part b is
