What is the buoyancy force acting on the body if the weight in air is 5 Newtons, and in water 2.4 Newtons.

The weight of the body is the force with which the body acts on the support (on the ground, on the place on which it stands, on the thread on which it is suspended). The action of the force is directed downward towards the ground.

A buoyant force acts on a body immersed in water, equal in value to the weight of the water displaced by it and directed against the direction of the action of the weight (gravity) of the body, that is, towards it, upwards.

It partially compensates for its value – a body immersed in water becomes “lighter” by the magnitude of the buoyancy force.

It can be determined by subtracting from the value of the body weight in the air – the value of its weight, measured in a submerged state.

In our case, the buoyancy force will be equal to – 5 N – 2.4 N = 2.6 N.
