Question

Which of the following statements are true.

• A. Larger the volume of a body submerged in a fluid, greater the upthrust.
• B. when the upthrust is greater than the weight of a body, the body sinks.
• C. The upthrust depends on the density of the fluid.
• D. The upthrust on a body acts in the upward direction.

Answer 1

Answer: (A), (C), (D)

The correct options are
A

Larger the volume of a body submerged in a fluid, greater the upthrust.

C

The upthrust depends on the density of the fluid.

D

The upthrust on a body acts in the upward direction.

• The magnitude of upthrust depends on the weight of the body or the force that is pushing the body down. So greater the force, larger the volume of a body submerged in a fluid, greater the upthrust.
• The upthrust depends on the density of the fluid. Greater the density greater is the upthrust.
• The upthrust, as we know is a reaction force so it acts in the upward direction.
