STATEMENT-1 : Two cylinders, one hollow (metal) and the other solid (wood) with the same mass and identical dimensions are simultaneously allowed to roll without slipping down an inclined plane from the same height. The hollow cylinder will reach the bottom of the inclined plane first.
STATEMENT-2 : By the principle of conservation of energy, the total kinetic energies of both the cylinders are identical when they reach the bottom of the incline.
STATEMENT-2 : By the principle of conservation of energy, the total kinetic energies of both the cylinders are identical when they reach the bottom of the incline.
View answer and explanation
Correct option: D
Statement - 1 is False, Statement-2 is True
Statement-1 is False, and Statement-2 is True. The solid cylinder reaches the bottom first because it has a lower moment of inertia. The total kinetic energies are the same due to conservation of energy.
