A solid sphere, a hollow sphere and a disc are released from the top of a frictionless inclined plane so that they slide down the inclined plane (without rolling). The maximum acceleration down the plane is
The maximum acceleration of the center of mass of a body along inclined plane in a downward direction is gsinθ.
Where, g=acceleration due to gravity
θ = angle of inclination of the plane.
This is independent of a property of the body.So the maximum acceleration is same for all the body
