1Two Rollers on the Same Incline: Shape Factor Beats Mass
In a practical revision session for Maharashtra HSC Physics, a teacher gives two rollers that look identical from outside. Roller A is a solid cylinder and roller B is a thin-walled hollow cylinder; both have mass 2.0 kg and outer radius 5.0 cm.
