A solid, uniform disc of mass M and radius R is able to rotate

without friction in the vertical plane about a horizontal axis through

its center of mass. Two small but heavy point particles of mass m1

and m2, where m1 > m2, are fixed to the disc at the very edge on

each side. If the disc is allowed to freely rotate, what is the angular

acceleration α the moment it is released from this position? Be sure

to include the direction. For your diagram draw the relevant physical

quantities on the provided figure. Hint: How many different moments

of inertia do you need to consider?
