A wire extends by `'l'` on the application of load `'mg'`. Then the energy stored in it is

A wire of length L extends by l on application of force F. Suppose the wire is cut into 3 equal parts and the same force is applied to one of them. Now the extension will be

A wire of length L extends by l on application of force F. Suppose the wire is cut into 3 equal parts and the same force is applied to one of them. Now the extension will be

A weight Mg is attached to the free end of a wire suspended from a rigid support. The wire is extended by l. The ratio of the elastic potential energy stored in the stretched wire to the work done by the weight Mg is

The extension of a wire by the application of load is 3 mm . The extension in a wire of the same material and length but half the radius by the same load is

The extension of a wire by the application of load is 3 mm . The extension in a wire of the same material and length but half the radius by the same load is

The extension of a wire by the application of a load is 2 mm. The extension in a wire of the same material and same length but half the radius by the same load is

If a spring extends by x on loading, then the energy stored by the spring is (if T is tension in the spring and K is spring constant)

If a spring extends by x on loading, then the energy stored by the spring is (if T is tension in the spring and k is spring constant)

If a spring extends by x on loading, then then energy stored by the spring is (if T is tension in the spring and k is spring constant)
