Question

Prove that the loss in weight of a body when immersed in a fluid is equal to the buoyant force, and this loss is because of the difference in pressure exerted by the fluid on the upper and lower surfaces of the submerged part of the body.

Options:
a. Archimedes' principle is not related to buoyancy.
b. The buoyant force is independent of the density of the fluid.
c. The loss in weight is due to gravitational forces only.
d. The loss in weight is not related to pressure differences.

Answer 1

The loss in weight can be proven by d. The loss in weight is not related to pressure differences.

How to prove the reason for the loss in weight ?

Archimedes' principle states that when a body is submerged in a fluid, it experiences an upward buoyant force that is equal to the weight of the fluid displaced by the body.

This principle is based on the concept of buoyancy, which is the upward force exerted by a fluid on a submerged or partially submerged object. The loss in weight of a body when immersed in a fluid is equal to the buoyant force because the buoyant force counteracts the gravitational force acting on the body.

This loss in weight is due to the buoyant force, not pressure differences on the upper and lower surfaces of the submerged part of the body.
