Question
A body of volume V and density ρ is kept completely immersed in a liquid of density ρL. If g is the acceleration due to gravity, then write expressions for the following:
(i) The weight of the body, (ii) The upthrust on the body,
(iii) The apparent weight of the body in liquid, (iv) The loss in weight of the body.

Solution
(i) Weight of the body = V ρ g
(ii) Upthrust on the body = V ρL g
(iii) Apparent weight of the body in liquid = V(ρ - ρL) g
(iv) Loss in weight of the body = V ρL g
