A wire is loaded by 6 kg at its one end, the increase in length is 12 mm . If the radius of the wire is doubled and all other magnitudes are unchanged, then increase in length will be

When a uniform wire of radius r, is stretched by a 2 kg weight, the increase in its length is 2.00 mm. If the radius of the wire is R/2 and other conditions remaining the same, the increase in its length is

When a uniform wire of radius r is stretched by a 2kg weight, the increase in its length is 2.00 mm . If the radius of the wire is r//2 and other conditions remain the same, the increase in its length is

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

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

When a weight of 10 kg is suspended from a copper wire of length 3 metres and diameters 0.4 mm , its length increases by 2.4 cm . If the diameter of the wire is doubled, then the extension in its length will be

In a wire of length L, the increase in its length is l . If the length is reduced to half, the increase in its length will be

In a wire of length L, the increase in its length is l . If the length is reduced to half, the increase in its length will be
