A solid sphere of radius R and density p is attached to one end of a mass-less spring of force constant k. The other end of the spring is connected to another solid sphere of radius R and density 3p. The complete arrangement is placed in a liquid of density 2p and is allowed to reach equilibrium. The correct statement(s) is (are) (A) the net elongation of the spring is 4Rpg 3k 8R'pg 3k (B) the net elongation of the spring is (C) the light sphere is partially submerged. (D) the light sphere is completely submerged.
