Solution

The correct option is A $F_{A}$ = $F_{B}$
As both have equal volume inside water, they will experience the same upthrust
$F_{T h r u s t} = ρ V g$ , where $ρ$ is density of water and $V$ is volume of spheres.
Hence, option A is correct.

Q. The A, B, and C vessels are filled with the liquid of the same height. The bottom area of A is equal to the bottom area of B and is less than the bottom area of C.
Which of the following relation is correct for the value of the force at the bottom?
(

F_{A}, F_{B} and F_{C}

are the force values at the bottom for A, B and C respectively.)

Three identical vessels A, B and C contain same quantity of liquid. In each vessel balls of different densities but same masses are placed. In vessel A, the ball is partly submerged; in vessel B, the ball is completely submerged but floating and in vessel C, the ball has sunk to the base. If $F_{A}$ , $F_{B}$ and $F_{C}$ are the total forces acting on the base of vessels A, B and C respectively, then

A sphere of iron and another of wood of the same radius are held under water. Let FA and FB are the uptrusts of iron and wood respectively.Compare the upthrust on the two spheres.

The correct option is A FA=FBAs both have equal volume inside water, they will experience the same upthrustFThrust=ρVg, where ρ is density of water and V is volume of spheres.Hence, option A is correct.
