Two smooth spheres, A & B of equals radius, lie on a horizontal table.

1.	Two smooth spheres, A & B of equals radius, lie on a horizontal table. A is of mass m & B is of mass 3m. The spheres are projected towards each other with velocity vectors 5hat(i) + 2hat(j) and 2hat(i) - 2hat(j) respectively & when they collide, the line joining their centres is parallel to the vector hat(i). If the coefficient of restitution between A and B is 1/3 Their velocities after impact are
Answer» `2HAT(i) + 2hat(J) , 3HAT(i) - HAT(j)` `2hat(i) - 2hat(j) , 3hat(i) + hat(j)` `hat(i) - hat(j) , 3hat(i) + hat(j)` `hat(i) - hat(j) , 3hat(i) - hat(j)` ANSWER :A
