JEE Main Physics question
Each question below contains an ASSERTION (Statement 1) and a REASON (Statement 2). Each question has 4 choices (a), (b), (c), (d), out of which ONLY ONE is correct.
**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 cylinders are identical when they reach the bottom of the incline.
Solution
Acceleration down the incline is . For the hollow cylinder giving ; for the solid cylinder giving . So the **solid** cylinder reaches first, not the hollow one
