The ratio of the accelerations for a solid sphere (mass ‘m’ and radius ‘R’) rolling down and incline of angle 'θ' without slipping and slipping down the incline without rolling is

For a round object rolling without slipping down an incliend surface, aaceleration is given by and for the same object slipping down for a solid sphere a2 = g(sinθ)For a solid sphere = 5/7
