Tension on a wire becomes 5 kg wt from 3 kg wt. .hence its length be come 1 mm from 0.6 mm. Find out the workdone for the increase of the length.

IF the tension in a wire increases gradually to 6kg, the elongation of the wire becomes 1.13mm. Calculate the work done.

When the load on a wire is increased from 3kg to 5kg, the elongation of the wire increases from 0.6mm to 1mm.How much work is done during this extension of the wire?

When a load of 10 kg is suspended from one end of a wire of length 1m, it increases in length by 0.1 cm. IF the Poisson's ratio for the material of the wire is 1/3 , then calculate the change in volume of the wire, cross-sectional area of the wire =0.1 cm^2 .

A wire (Y =2xx10^11N//m^2) has length 1m and area 1mm^2 . Calculate the work required to increase its length by 2mm.

The length of a potentimeter wire is 10cm . A cell of emf E is balanced at a lenth (10)/(3) cm from the positive end of the wire .If the length of the wire is increased by 5 cm , at what distance (in cm ) from positive end will the same cell give a balance point ?

When a load of 10 kg is hung from one end of a wire of length 5 m, the wire elongates by 5 mm. IF the young modulus for the material of the wire is 9.8 times 10^10 N.m^-2 , then find the area of cross section of the wire. [g=9.8 m.s^-2 ]

IF the work done in stretching a uniform wire, of cross section 1mm^2 and length 2m, by 1mm is 0.05 joule, find the young's modulus for the material of the wire.
