प्रश्न
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.
उत्तर
If F1 < F2 or F1 = F2, the body will float.
If F1 > F2, the body will sink.
