Selina Solutions Class 9 Physics Solutions for Exercise 5A in Chapter 5 - Chapter 5 Upthrust In Fluids Archimedes Principle And Floatation

Question 17 Exercise 5A

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 backing on the body and state the conditions when the body will float or sink.

Answer:

The body floats if F1 is lesser than F2 or if both are equal. The body sinks if F1 is greater than F2
