1.	Consider a disc rotating in the horizontal plane with a constant angu lar speed omega about its centre O. the disc has shaded region on one side of the diameter and an unshaded region on the other side as shown in Fig. 5.111. when the disc is in the orientation as shown, two pebbles P and Q are simu ltaneously projected at an angle towards R. the velocity of projection in the y-z plane and is same for both pebbles with respect to the disc. Assume that i they land back on the disc before the disc has completed 1/8 rotation, ii their range is less than half the disc radus, and iii omega reamisn constant throughout. then
Answer» P lands inthe shaded REGION and Q in the unshaded region. P lands in the unshaded region and Q in the shaded region. BothP and Q LAND in the unshaded region Both P and Q land in the shaded region Answer :c
