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

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

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

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

The radius of a wire is decreased to one-third. If volume remains the same, length will increase by ?

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

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