The force of buoyancy is equal to
- Weight of the body
- Weight of the liquid displaced by the body
- apparent weight of the body
- viscous force
Correct Answer: Option(b)
Solution: Consider a body being completely immersed in a liquid.
The fluid then attains equilibrium & part of fluid substituting for the body, is also in equilibrium.
Forces acting on substituting fluid are
(a) weight of part of fluid
(b) resultant buoyant force
As its in equilibrium
