Questions
A solid disc is kept on a rough horizontal surface as shown in figure. A horizontal force is applied on the disc at point P as shown. Assuming sufficient force is there to prevent slipping,
detailed solution
Correct option is A
The applied force F produces an anticlockwise moment about the centre of mass C. Slipping can be prevented if the friction force produces clockwise moment about the centre of mass C. This is possible only when the friction force is backward.Talk to our academic expert!
