If a copper wire of length 0.9 m and cross section `1mm^(2)` is stretched by a load of 1 kg then the extension in the wire will be
`(Y_(c )=1.2xx10^(11)N//m^(2) and g=10m//s^(2))`

When a copper wire of area of cross section 1 mm^(2) is stretched by a force of 10N. Then the work done per unit volume in stretching the wire is (Y=1.2xx10^(11)Nm^(-2))

A one metre long wire having area of cross-section 1 mm^2 is stretched by a mass of 3 kg. Calculate the increase in length. Take Y = 2 xx 10^11 N m^-2

A copper wire of length 4.0 mm and area of cross-section 1.2 cm^(2) is stretched with a force of 4.8 xx 10^(3) N. If Young's modulus for copper is 1.2xx10^(11) N//m^(2) , the increases in the length of the wire will be
