Question

Which of the following factors affect the upthrust acting on a body submerged in a fluid?

• A. The density of the liquid
• B. The volume of the body submerged
• C. The mass of the fluid
• D. The colour of the object submerged

Answer 1

Answer: (A), (B)

The correct options are
A The density of the liquid
B The volume of the body submerged

Upthrust or buoyant force depends on the density of the fluid, as denser fluids exerts more upthrust. It also depends on the weight and volume of the body submerged in the liquid, i.e. the density of the body.
