Block 1 of mass \(m\) and Block 2 of mass \(3m\) are connected by a light string that passes over a pulley of mass \(M\) and radius \(R\), as shown. The pulley is a uniform disk with rotational inertia \(I = \dfrac{1}{2}MR^2\) and rotates with negligible friction. The system is released from rest, and Block 2 accelerates downward. The experiment is repeated using a pulley with the same radius \(R\) but a mass of \(2M\). How do the magnitude of the acceleration of Block 2 and the tension in the string segment attached to Block 2 in the second experiment compare to the first experiment?

	Acceleration of Block 2	Tension in segment for Block 2
(A)	Decreases	Increases
(B)	Decreases	Decreases
(C)	Increases	Increases
(D)	Stays the same	Stays the same
