AIIMS 2018 Physics Rolling Motion Assertion Reason Question

Option A is correct because both the assertion and reason are true; a rolling sphere does indeed slow down due to energy loss from friction, which causes deformations at the contact point. The reason accurately explains that the deformation leads to a misalignment of the normal force, resulting in an angular deceleration that contributes to the sphere's eventual stop. Option B is incorrect because the reason does explain the assertion. Option C is incorrect as both statements are true, and option D is false since the assertion is valid. Understanding the interplay between rolling motion and frictional forces is crucial in mechanics, as it illustrates how energy is dissipated in real-world scenarios.
