Question

In which direction does the buoyant force acts?

• A. Upward
• B. Downward
• C. In the direction of weight
• D. Can't be determined

Answer 1

The correct option is A

Upward

Buoyant force is the upward force which the liquid exerts when any object is immersed into it. Its magnitude depends on the weight of liquid displaced by the body.

Buoyant force = $v_b{\rho }_{l}g$ where $v_b$ is volume of body immersed in liquid, ${\rho }_l$ is density of liquid, $g$ is accelaration due to gravity.
