Question

Select One Option Correct from the following :A solid sphere of radius R and density$\rho$ is attached to one end of a massless spring of force constant k. The other end of the spring is con- nected to another solid sphere of radius R and density $3\rho$.The complete arrangement is placed in a liquid of density $3\rho$ and is allowed to reach equilibrium. The correct statement(s) is (are)
(A) the net elongation of the spring is $\frac{4 \pi R^3 \rho g}{3k}$
(B) the net elongation of the spring is $\frac{8 \pi R^3 \rho g}{3k}$
(C) the light sphere is partially submerged.
(D) the light sphere is completely submerged.
