A cylinder having radius 0.4 m, initially rotating (at t = 0) with w0 = 54 rad/sec is placed on a rough inclined plane with q = 37° having friction coefficient m = 0.5. The time taken by the cylinder to start pure rolling is :
- 5.4 sec
- 1.4 sec
- 1.2 sec
- 1.8 sec
The correct answer is: 1.8 sec

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.
