A sphere of diameter $7\,\, cm$ and mass $266.5 \,\,gm$ floats in a bath of a liquid. As the temperature is raised, the sphere just begins to sink at a temperature $35^o C$. If the density of a liquid at $0^o C$ is $1.527 \,\,gm/cc$, then neglecting the expansion of the sphere, the coefficient of cubical expansion of the liquid is$f$ :

  • A

    $8.486 × 10^{-4}\,\, per ^0C$

  • B

    $8.486 × 10^{-5}\,\, per ^0C$

  • C

    $8.486 × 10^{-6}\,\, per^ 0C$

  • D

    $8.486 × 10^{-3}\,\, per^ 0C$
