Assertion : The buoyant force on a submerged rigid object can be considered to be acting at the centre of mass of the object.
Reason: For a rigid body a force field distributed uniformly through its volume can be considered to be acting at the centre of mass of the body.
143325 A vessel contains liquid of density $\rho$ over another liquid of density $m \rho$ (where $m$ is any number). A homogeneous sphere floats with $\frac{1}{n}$ times (where $\eta$ is any number) of its volume in liquid of density $\mathrm{m} \rho$ and remaining portion in liquid of density $\rho$. The density of the material of the sphere is)
