There is some change in length when a 33000 N tensile force is applied on a steel rod of area of cross-section `10^-3 m^2`. The change of temperature required to produce the same elongation, if the steel rod is heated, is (The modulus of elasticity is `3 xx10^11 N m^-2` and the coefficient of linear expansion of steel is `1.1 xx10^-5//^@c`)

`20^(@)C`

`15^(@)C`

`10^(@)C`
