Question

A body held completely immersed inside a liquid experiences two forces:

(i) F1, the force due to gravity and

(ii) F2, the buoyant force.

Draw a diagram showing the direction of these forces acting on the body and state the condition when the body will float or sink. 

Short/Brief Note

Solution

If F1 < F2 or F1 = F2, the body will float.

If F1 > F2, the body will sink.
