Question

For a cylinder of density 1.5 g cm", buoyant force is 4 N inside a liquid of density d. Find
the buoyant force for the same inside a liquid of density 3d.​

Answer 1

Explanation:

Buoyancy force is equal to weight of liquid displaced and ρ

liquid=d

F=Vρ

liquid

g=Vdg=4N

now when the density become 3d

F

1

=V×ρ

new

g=V×3d×g=3F

F

1

=3×4=12N
