We measure the uplift force with a dynamometer

Measure the buoyant force acting on the body in the water using a dynamometer. Answer the question.

What are we dealing with here

Buoyancy acts on bodies immersed in water. Buoyancy can be measured by comparing the weight of a body suspended in the air and a body submerged in water, i.e. the force with which they act on the suspension device.

How we conduct the experiment

If we hang a weight on the end of a dynamometer, the dynamometer shows the weight of the body, i.e. the force with which the Earth pulls the weight towards itself. If we place a weight suspended at the end of the dynamometer in the water, it will be affected by a buoyant force in addition to the force of gravity. Therefore, the dynamometer starts to show less power.
