Question

When a body is placed in a liquid, the buoyant force experienced by it is equal to the:
A. Weight of liquid displaced
B. Density of body
C. Volume of body
D. Density of liquid

Answer 1

A. Weight of liquid displaced

Answer 2

The buoyant force experienced by a body placed in a liquid is equal to the weight of the fluid (liquid) displaced.

• The buoyant force or upthrust is the force applied by the fluid in a direction opposite to the gravity.
• The magnitude of this force is equal to the weight of the fluid displaced.
• A body feels lighter when immersed in fluid because of buoyant force.
• The difference between the actual weight of a body and the buoyant force is the apparent weight of the body.
• Hence, the correct answer is an option (A).
