A body of mass m rests on horizontal surface. The coefficient of friction between the body and the surface is \[\mu .\] If the mass is pulled by a force P as shown in the figure, the limiting friction between body and surface will be [BHU 2004]

\[\mu \,\left[ mg-\left( \frac{\sqrt{3}\,P}{2} \right) \right]\]

\[\mu \,\left[ mg+\left( \frac{P}{2} \right) \right]\]

\[\mu \,\left[ mg-\left( \frac{P}{2} \right) \right]\]
