1.	Consider the moment of inertia I of the rigid homogerneous disc of mass M as shown in the figure about an axis through its centre (different shadings only differentiate the two parts of the disc each with equal mass M//2). Which one of the following statements concerning I is correct?
Answer» The inner and outer PARTS of the disc, each with mass `M//2`, contribute equal AMOUNTS to /. The inner part of the disc contributes less to// than outer part. The inner part of the disc contributes less to//than the outer part. The inner part of the disc MAY contribute more or less to//depending on the actul numerical value to the mass M of the disc. Answer :C
