Question

What do you mean by buoyant force?

Answer 1

1. Buoyant force: It is the upward force experienced by a body when partially or completely immersed in a fluid.
2. The property of the fluids to apply upward force on the immersed body is called buoyancy.
3. It is given by $$\begin{gathered} F_b=-\rho gV \\ {F}_b=buoyantforce \\ \rho =fluiddensity \\ g=accelerationduetogravity,V=fluidvolume \end{gathered}$$
4. The buoyant force depends on the density of the fluid and the volume of the body immersed, which is the same as the volume of fluid displaced by the body.
