Question

The vessels A and B of equal volume and weight are immersed in water to depth $h$ . The vessel A has an opening at the bottom through which water can enter. If the work done in immersing A and B are $W_{A}$ and $W_{B}$ respectively, then

W_{A} = W_{B}

Solution

The correct option is A $W_{A}$ < $W_{B}$
Because water enters into the vessel A, it becomes heavier. Gravity helps it sink. External work required for immersing A is obviously less than that for immersing B.

The vessels A and B of equal volume and weight are immersed in water to depth h. The vessel A has an opening at the bottom through which water can enter. If the work done in immersing A and B are WA and WB respectively, then

The correct option is A WA < WBBecause water enters into the vessel A, it becomes heavier. Gravity helps it sink. External work required for immersing A is obviously less than that for immersing B.
