Question

The equation for bouyancy force on a fully submerged object of volume V and mass M is given by: OF) = PwVg OF) = Pwg/V OF, = Mg

Answer 1

`OF=\rho _wVg`

Step-by-step explanation:

The bouyancy force an object feels (OF) when submerged ina fluid is always the weight of the liquid the object displaces. This weight will be the mass of fluid displaced (
`m_d`) multiplied by the acceleration of gravity g. The mass displaced will be the density of the fluid
`\rho_w` multiplied by the volume of fluid displaced
`V_d`. If the object is fully submerged, then this volume will be the same as the volume of the object V. We write all these steps in equations:

`OF=m_dg=\rho _wV_dg=\rho _wVg`
