A body of mass m rests on horizontal surface. The coefficient of friction between the body and the surface is m. If the mass is pulled by a force P as shown in the figure, the limiting friction between body and surface will be:
- \(\mu m g\)
- \(\mu\left[m g+\left(\frac{P}{2}\right)\right]\)
- \(\mu\left[m g-\left(\frac{P}{2}\right)\right]\)
- \(\mu\left[m g-\left(\frac{\sqrt{3} P}{2}\right)\right]\)
Answer
(C) [m g- ( P 2 ) ]
