A wire having Young's modulus `2 xx 10^(11)N//m^(2)` is stretched by a force. If the energy stored per unit volume of the wire is `40 "joule"//m^(3)`, then the stress produced in the wire is

The stored energy per unit volume of a stretched wire is

On stretching a wire, the elastic energy stored per unit volume is,

When a wire is stretched by a force the strain produced in the wire is 2 xx 10^(-4) . If the energy stored per unit volume of the wire is 4 xx 10^(4) "joule"//m^(3) then the Young's modulus of the material of the wire will be,

A wire having Young's modulus 1.2xx10^(11) N//m^(2) is subjected to the stress of 2.4xx10^(7) N//m^(2) . If the length of the wire is 10m, the extension produced in it is

Young's modulus of a wire is 2 xx 10^(11) N//m^(2) . The wire is stretched by a 5 kg weight. If the radius of the wire is doubled, its Young's modulus

If 'S' is stress and 'Y' is young's modulus of material of a wire, the energy stored in the wire per unit volume is
