A piece of metal has a weight of 49 {gm} in air and 39 {gm} in a liquid of density 1.2 \times 10^{3} {kg} \/ {m}^{3} {kept} at 32{ }^{\circ} {C}. When the temperature of the liquid is raised to 42{ }^{\circ} {C} the metal piece has a weight of 40 {gm}. If the density of the liquid at 42^{\circ} {C} is 1.0 \times 10^{3} {kg} \/ {m}^{3}, then the coefficient of linear expansion of the metal is

Correct Answer is : 83×10−3∕∘C

\frac{8}{3} \times 10^{-3} \/{ }^{\circ} {C}

\frac{11}{3} \times 10^{-3 \/{ }^{\circ} {C}}

\frac{1}{3} \times 10^{-4} \/{ }^{\circ} {C}

\frac{4}{3} \times 10^{-3 \/{ }^{\circ} {C}}

A piece of metal has a weight of 49gm in air and 39gm in a liquid of density 1.2×103kg∕m3kept at 32‌∘C. When the temperature of the liquid is raised to 42‌∘C the metal piece has a weight of 40gm. If the density of the liquid at 42∘C is 1.0×103kg∕m3, then the coefficient of linear expansion of the metal is
