Question

Buoyancy force and centre of buoyancy

Answer 1

Rotational stability depends on the relative lines of action of forces on an object. The upward buoyancy force on an object acts through the center of buoyancy, being the centroid of the displaced volume of fluid. The weight force on the object acts through its center of gravity.

Answer 2

Answer:

$\huge \bf{Buoyancy \: force} \\ \\ \implies \: \red{\bf{Buoyancy \: force \: is \: the \: resultant \: of \: }} \\ \bf{normal \: contact force \: due \: to \: surrounding} \: \\ \ \bf{ \: medium .}\\ \\ \bf{Buoyancy \: force \: (B) = f 1 - f2 } \\ \\ or, \: \\ \\ B = \rho \: g \: v \: \\ \\ \bf{ \rho \: \: \: be \: the \: density \: of \: liquid.} \\ \\ \bf{v \: \: is \: the \: volume \: of \: liquid \: displacment.}$
