MCQ
When a body floats in a liquid, the buoyant force acting on it is:
Unit-5 Pressure and Deformation in Solids
A
equal to the weight of the body
B
greater than the weight of the body
C
less than the weight of the body
D
always zero
Explanation
For a floating body the upward buoyant force balances its weight, so the two are equal.
