Question

A ball of mass m is tied to a string that is wrapped around a pulley. The pulley rotates without friction about an axle passing through the center of the pulley. When the system is released from rest, the ball accelerates down. In addition to the mass of the ball, what determines the ball's acceleration? Select the two correct answers. The mass of the pulley and the radius of the pulley The mass of the pulley, how that mass is distributed, and the radius of the pulley The mass of the pulley and how that mass is distributed What planet the system is on

Explanation / Answer

here acceleration becomes a=(2/3)g

its depends on the gravity and the at which it is plsced nothing but the position of the axis .

henc from the given option option D is the right option.
