The circular portion of part 1 contacts the curved portion of part 2. Neglect friction between pert land part 2. Considers bodies to be in the orientations shown. Could the reaction of part 2 on part 1 be as shown? (a) I is possible, II is possible (b) I is possible, II is impossible (c) I is impossible, II possible (d) I is impossible, II is impossible (e) Cannot say without more information Solution Answer id Option C. Since the reaction force cannot be a curve and it acts at certain angle from the surface. So I is impossible and Option II is possible.
