Which among the following systems can be sufficiently described by classical physics?

Step-by-step solution

Classical physics is sufficient to describe the motion of macroscopic objects moving at non-relativistic speeds. A cricket ball and a dust particle are macroscopic objects, so their motion can be described by classical mechanics. A hydrogen atom and a neutron transforming into a proton are microscopic and subatomic systems, respectively. These require quantum mechanics for an accurate description. Therefore, the motion of a cricket ball and a dust particle can be sufficiently described by classical physics.
