Answer 2

$\huge\blue{\bold{\underline{\underline{Hint:}}}}$

Initially both the balls one made of iron and the other made of rubber are kept on the floor of the moving train. The floor is frictionless and thus, there will be no frictional force. The train suddenly stops, so we can use the concept of inertia and Newton’s first law.

$\huge\blue{\bold{\underline{\underline{step-by-step -answer:}}}}$

Yes. the balls will start rolling in the direction in which the train was moving. This happens because of the inertia. - Inertia is defined as the inherent property of the body which opposes any change in its state of rest or motion. Inertia wants if a body is at rest, it should remain at rest. If a body is in motion it should remain in motion

Since the masses of the balls are not the same, therefore, forces are not same on both the balls. Thus, the balls will move with different speeds. The inertia of an iron ball is greater than a rubber ball because it is more massive than the rubber ball. Thus, the rubber ball will move fast.
