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 of length 2 ,m and radius 2 mm is stretched by 2.5 mm when a load of 5 kg is suspended from it Another wire of the same material put of length 1 m and radius 1 mm is attached below the load and a load of 3kg is suspended from this wire what is the total increase in length and what are the individual exensions of the wirs ?

A mass of 0.5 kg is suspended from wiere, then length of wire increase by 3 mm then work done

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 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

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

A copper wire and a steel wire of the same length and same cross-section are joined end to end to form a composite wire. The composite wire is hung form a rigid support and a load is suspended form the other end. If the increses in length of the composite wire is 2.4mm . then the increases in lenghts of steel and copper wires are
