Question

A body of volume V and density ρ is completely immersed in a liquid of density ρ_L . If g is the acceleration due to gravity, which of the following expressions are correct :

1) weight of the body = Vρg

2) upthrust on the body = VρLg

3) apparent weight of the body in liquid = VρLg

4) the loss in weight of the body = V(ρ-ρL)g

• A. only 2 and 3
• B. only 4
• C. both 1 and 2
• D. only 1

Answer 1

The correct option is C

both 1 and 2

The expression for the apparent weight of the body in liquid = V(ρ-ρL)g and the loss in weight of the body = VρLg
