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 $3 \times 10^{11}\;N/m^2$ and the coefficient of linear expansion of steel is $1.1 \times 10^{-5}/^{\circ}C)$. - Clay6.com, a Free resource for your JEE, AIPMT and Board Exam preparation
