Two smooth balls A and B, each of mass m and radius R, have their centre at (0,0,R) and at (5R,–R,R) respectively, in a coordinate system as shown. Ball A, moving along positive x axis, collide with ball B. Just before the collision, speed of ball A is 4 m/s and ball B is stationary. The collision between the balls is elastic.

Velocity of the ball A just after the collision is 3j) m/s

A carpet of mass 'M' made of inextensible material is rolled along its length in the form of a cylinder of radius 'R' and is kept on a rough floor. The carpet starts unrolling without sliding on the floor when a negligibly small push is given to it. The horizontal velocity of the axis of the cylindrical part of the carpet when its radius reduce to R/2 will be:

An object is placed infront of a converging lens at a distance equal to twice the focal length f subscript 1 end subscript of the lens. On the other side of the lens is a concave mirror of focal length f subscript 2 end subscript separated from the lens by a distance 2 open parentheses f subscript 1 end subscript plus f subscript 2 end subscript close parentheses. Light from the object pass rightward through the lens, reflects from the mirror, pass leftward through the lens and forms a final image of the object.
