force which makes a heavy object lighter in water.

Answer 1

Answer:

Fluid pressure acts on a object from upward force known as buoyant force. which makes a heavy object lighter in water.

Explanation:

The object is seemed to be lighter than the original weigh of the object.

The buoyant force is depends upon the factor-

• Density of liquid (In which the object is immerged).
• Volume of object (immersed in liquid).

General formula for Buoyant force is-

$Density=\frac{mass}{volume}$

If we increase the density of water and volume of the object than the buoyant force is also increases.

The upward force is known as upthrust force.
