When a weight of `5 kg` is suspended from a copper wire of length `30 m` and diameter `0.5 mm`, the length of the wire increases by `2.4 cm`. If the diameter is doubled, the extension produced is

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

when a weight of 10 kg is suspended from a copper wire of length 3m and diameter 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

An object of mass 5 kg is suspended by a copper wire of length 2 m and diameter 5 mm. Calculate the increase in the length of the wire. In order not to exceed the elastic limit, what should be the minimum diameter of the wire ? For copper, elastic limit =1.5 xx 10 ^(9) "dyne" //cm ^(2) , (Y) = 1.1 xx 10 ^(12) "dyne"//cm^(2).

Determine the resistance of a copper wire having a length of 1 km and diameter of 0.5 mm
