Question

A cylinder is floating in two liquids ad shown in figure. Choose the correct options

• A. Net force on cylinder by liquid $1$ is zero.
• B. Net force on cylinder by liquid $1$ is non-zero.
• C. Net force on cylinder by liquid $2$ is equal to the upthrust.
• D. Net force on cylinder by liquid $2$ is more than the upthrust.

Answer 1

Answer: (A), (D)

Net force on cylinder by liquid $1$ is zero.
Net force on cylinder by liquid $2$ is more than the upthrust.

Here, net force due to liquid 1 is zero, because forces from both sides of the cylinder nullyfies each other.

And to balance the atmospheric force and weight of the cylinder liquid 2 will provide force.

So. $F_{liquid2}-F_{atm}=$upthrust

$\therefore F_{liqui{d}_2}>upthrust$

The correct answers are $A$ and $D$
