An elastic spring of unstretched length L and spring constant K is stretched by a small length x. It is further stretched by another small length y. the work done in second stretcing is

An elastic spring of unstretched length L and force constant K is stretched by amoun t x .It is further stretched by another length y The work done in the second streaching is

A string of length L and force constant k is stretched to obtain extension l. It is further stretched to obtain extension l_(1) . The work done in second streching is

STATEMENT-1: An elastic spring of force constant k is stretched by a small length x. The work done in extending the spring by a further length x is 2kx^(2) . because STATEMENT-2: The work done in extending an elastic spring by a length x is proportional to x^(2) .

A wire fixed at the upper end stretches by length l by applying a force F. The work done in stretching is

A piece of elastic was stretched by 24% to a length of 31 cm .find its unstretched original length

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) .
