Vedclass · Answer

(D) Since the inclined plane is frictionless,there is no rolling motion,and the objects will only slide down the plane.For an object sliding down a frictionless inclined plane,the only force acting along the plane is the component of gravitational force,$F = mg \sin 	heta$.According to Newton's second law,$F = ma$,so $mg \sin 	heta = ma$.Therefore,the acceleration is $a = g \sin 	heta$.Since this acceleration depends only on the acceleration due to gravity $g$ and the angle of inclination $	heta$,it is independent of the shape or mass of the object.Hence,the acceleration is the same for the solid sphere,the hollow sphere,and the ring.

$A$ solid sphere,a hollow sphere,and a ring are released from the top of an inclined plane (frictionless) so that they slide down the plane. Then,the maximum acceleration down the plane is for (no rolling):
