When the weight of the fluid displaced is less than the weight of the solid body then:

When the weight of the fluid displaced is less than the weight of the solid body then: Correct Answer The body sinks in a fluid

Explanation:​

Archimedes principle: 

• It is used to explain the law of flotation or upward thrust experienced when immersed in a fluid. 
• The principle of Archimedes states “When a body is immersed in a liquid, an upward thrust, equal to the weight of the liquid displaced, acts on it.”

• The flotation and sinking of an object are dependent upon the relative density with each other.
  • If the density of the object is more than the density of the liquid, the object will sink.
  • On the other side, if the density of an object is less than the liquid, then it will float over it.
  • If the density of the object and liquid is equal to each other, they are in equilibrium and float and sink both at the same time
  • Therefore, the sinking or floating of an object depends on the difference in density of objects and liquid.

Weight = m × g = ρ × g × V

• If the upthrust force (equal to weight) exerted on the body by the fluid is greater than the weight of the body, then the body floats. While, if upthrust is lesser, then the body sinks.
