Question

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. $F_A=F_B=F_C$
• B. $F_A<F_B<F_C$
• C. $F_A=F_B<F_C$
• D. $F_A>F_B>F_C$

Answer 1

The correct option is A $F_A=F_B=F_C$

In all given case the weight of the body is balanced by buoyency force so buoyency force will be same in all three cases as weight of the body is same in all situations.
