Question

Because buoyant force act in a direction opposite the force of gravity the net force acting on an object submerged in a fluid such as water is smaller than the objects weight.

• A. True
• B. False

Answer 1

The correct option is A True

1-According to Archimedes' principle the loss in the weight of the object completely or partially submerged in a fluid is equal to the weight of the liquid displaced by it.
2-This happens because of the buoyant force acting in the direction opposite to the direction of the weight of the body.

3-Buoyancy force/loss in weight/weight of the liquid displaced is $F={\rho }_w\times g\times V.$

where The density of the fluid is ${\rho }_w.$

Acceleration due to gravity is $g=9.81m/s^2$

The volume of liquid displaced is $V.$

Hence, the given statement is true.
