Two smooth spheres A and B, of equal radius but mass m and M, are free to move on a horizontal table. A is projected with speed u towards B which is at rest. On impact, the line joining their centers is inclined at an angle θ to the velocity of A before impact. If e is the coefficient of restitution between the spheres If A's path after impact is perpendicular to its path before impact then coefficient of restitution is found to be 1/n, find n. [Given: m = 5kg, M = 10 kg,\[\theta =30{}^\circ \]]
