Questions
A solid sphere, solid cylinder and a disc are allowed to roll down from the top of an incline plane from the same height. Then
detailed solution
Correct option is C
Acceleration of a round object rolling without slipping down a rough inclined surface having inclination θ with horizontal is given by a = gsinθ / (1+ Ic /mr2)For solid sphere, Ic = 2/5 mR2.: a1 = 5/7 g sin θFor solid cylinder , Ic = 1/2 mR2.: a2 = 2/3 g sin θFor Solid disc , Ic = 1/2 mR2.: a3 = 2/3 gsinθSince a1 > a2 = a3 , option - (3) is correct.Talk to our academic expert!
