0^{\circ} \mathrm{C}

, the densities of a cork and a liquid in which the cork floats are

\mathrm{d}_1

and

\mathrm{d}_2

respectively. The coefficients of expansion for the material of the cork and the liquid are

\gamma

and

100 \gamma

respectively. If the cork sinks when temperature of liquid is

\mathrm{t}^{\circ} \mathrm{C}

, then ratio

\left(\mathrm{d_2 / d}_1\right)

View answer and explanation

Correct option: A

\frac{1+100 \gamma \mathrm{t}}{1+\gamma \mathrm{t}}

Option A is correct because it represents the ratio of densities considering the thermal expansion of both the cork and the liquid.
