A uniform cylindrical body of radius r has a conical nose. The length of the cylindrical and conical parts are 4r and 3r respectively. Mass of the conical part is M. The body rests on a horizontal surface as shown. A ring of radius r2 is to be tightly fitted on the nose of the body. What is maximum permissible mass of the ring so that the body does not topple?

A disc of mass m and radius R lies flat on a smooth horizontal table. A mass less string runs halfway around it as shown in figure. One end of the string is attached to a small body of mass m and the other end is being pulled with a force F. The circumference of the disc is sufficiently rough so that the string does not slip over it. Find acceleration of the small body.
