When something is floating in water..?

Question

what force is pushing it down, and what force is pushing it up?

Answer 1

Its weight

F = mg

(=9.8 times its mass)

is pushing it downwards

And buoyant force

F = ρVg

(for water, =9.8 times its volume, coz ρ=1)

pushes it upwards.

g = 9.8 m/s²

m = mass of the body

V = its volume

ρ = density of the liquid (not of object)

Answer 2

Pressure of the atmosphere pushing it down and the buoyant force of the water pushes up
