Question

what is buoyancy? Explain the factors affecting it?

Answer 1

Dear Student

BUOYANCY is an upward force acting on an object when it is in water.

Factors affecting the buoyant force are:
(a) Volume of the body immersed in liquid.
(b) Density of liquid. (Buoyant force is directly proportional to the density of the fluid in which an object is immersed.)
(c) Acceleration due to gravity.

Factor affecting buoyancy force:

F_B = ρV g

Where ρ = density of fluid

V = volume of fluid displaced

g = acceleration due to gravity.

Hence the force of buoyancy depends on the density of fluid and the volume of fluid displaced.
