Question

A stone is placed inside a container . The normal recation between the stone and the container is n1

Answer 1

Your question seems to be incomplete. Your complete question is-

A stone is placed inside a container. The normal reaction between the stone and the container is  N₁. Now a liquid is poured inside the container such that normal reaction between stone and the container is N₂, then (Assume no liquid between stone and container at the contact surface)  

a) N₂

b) N₂>N₁

c) N₂=N₁

d) None of these

The correct relation will be N₂ > N₁

Given-

• The normal reaction between stone and container = N₁
• After liquid is poured then normal reaction will be = N₂

The normal reaction will be increased by increase of force of the weight of the liquid on top of the stone so there will be no buoyancy as there is no water between stone and base.
