Question
A body of mass ‘m’ is floating in a liquid of density ‘p’
what is the apparent weight of body?
Solution
Mass of body = m
Density of liquid = ρ
Apparent weight of body = Weight of body in air – Weight of liquid displaces by body.
When a body floats in the liquid, then weight of the body in a liquid is equal to weight of liquid displaced by the body.
⇒ Apparent weight of body = 0
