A wire is suspended by one end. At the other end a weight equivalent to 20 N force is applied. If the increase in length is 1.0 mm, the increase in energy of the wire will be

If a load of 9 kg is suspended on a wire, the increase in length is 4.5 mm . The force constant of the wire is

If one end of a wire is fixed with a rigid support and the other end is stretched by a force of 10 N, the increase in length is 0.5 mm. The ratio of enegry of the wire and the work done in displacing it through 1.5 mm by the weight is

If one end of a wire is fixed with a rigid support and the other end is streched by a force of 10N , then the increae in length is 0.5mm . The ratio of the energy of the wire and the work done in displacing it through 0.5mm by the weight is

If one end of a wire is fixed with a rigid support and the other end is streched by a force of 10N , then the increae in length is 0.5mm . The ratio of the energy of the wire and the work done in displacing it through 0.5mm by the weight is

Increase in length of a wire is 1 mm when suspended by a weight. If the same weight is suspended on a wire of double its length and double its radius, the increase in length will be

A wire suspended vertically from one end is stressed by attaching a weight of 200N to lower end the weight stretched the wire by 1 mm. the elastic energy stored the wire is

A composite wire is prepared by joining a tungsten wire and steel wire Both the wires are of the same length and same area of cross section. If this composite wire is suspended to a rigid support and a force is applied to its free end, it gets extended by 3.25 mm. Calculate the increase in length of tungsten wire and steel wire separately.

A wire of length L and radius r is clamped at one end. On stretching the other end of the wire with a force F, the increase in its length is 1. If another wire of same material but of length 2L and radius 2r is stretched with a force 2F, the increase in its leagth will be

A wire of length L and radius r is clamped at one end. On stretching the other end of the wire with a force F, the increase in its length is 1. If another wire of same material but of length 2L and radius 2r is stretched with a force 2F, the increase in its leagth will be
