AIIMS 2019 Physics Kinetic Energy of Rotation MCQ Question

In the motion of a disc, the total energy (E) consists of both translational kinetic energy (TKE) and rotational kinetic energy (RKE). For a disc rolling without slipping, the relationship between these energies is such that TKE is equal to RKE, leading to a ratio of total energy to rotational kinetic energy of 1:1. Other options are incorrect because they suggest different relationships that do not hold true for a disc in pure rolling motion, where both forms of kinetic energy contribute equally to the total energy.
