Question

a solid sphere and a hollow sphere having same destiny and radius are rolling down an inclined plane. which one of them will reach first ?​

Answer 1

The solid sphere

Step-by-step explanation:

So when comparing the spheres, both spheres have the same density and have the same radius which would they are the same size so the only factor to vary them is mass. The solid sphere is filled and thus heavier compared to the hollow sphere which has lighter air. As a result, the solid sphere will be pulled down by gravity more and reach the bottom first.

Answer 2

The solid sphere.

Step-by-step explanation:

The moment of inertia for hollow sphere is larger, thereby having a greater resistance to motion. Thus the solid sphere will have greater speed.
