Question

An object weighing 84 g has a volume of $60c{m}^3$. Calculate the mass of the water displaced by the object when it is immersed completely in water.

• A. 504 g
• B. 240 g
• C. 60 g
• D. 120 g

Answer 1

The correct option is C 60 g

mass of water displaced would be equal to the force of buoyancy acting on it according to archimedies principle.

so buoyant force = (volume of solid immersed )( density of liquid )(g)

= (60}(1)(g) = 60 g ( density of water =$1gc{m}^3$)

hence option (C) is correct
