Question

When a body is immersed in a fluid it experiences a loss in its weight due to an upward force . Is the magnitude of this force the same in all fluids for a given body ? Elaborate give reason and explain with example

Answer 1

upthrust is the force applied on a body by the fluid when it is completely or partially immersed in a fluid. the magnitude of the upthrust is not same in all fluids because the upthrust by the fluid is proportional to the density of the fluid. as we know that fluid refers to both gases and liquids.
we can take an example of air and water and it is found that the weight of the body in air differs from the weight of the body in water.
because the density of air differs from the density of water
