An endless inextensible string passes over two small smooth pegs A and B, AB being horizontal, two particles of mass M and m (M > m) are attached to the string. The particle of mass m is released when it is in level with the pegs. As it comes down M rises up vertically. If and when they cross each other

A ray of light parallel to the axis of a converging lens (having focal length f) strikes it at a small distance ‘h’ from its optical centre. A thin prism having angle q and refractive index m is placed normal to the axis of lens at a distance ‘d’ from it. What should be the value of m so that the ray emerges parallel to the lens axis.
