Body of mass 35 kg, is placed on a horizontal surface whose coefficient of friction 0.5. Find the frictional force acting on it. (\[g=10m\text{ }{{s}^{-2}}\])

Answer:

Here, mass of the body,\[m=35\text{ }kg,\] Acceleration due to gravity,\[g=10\text{ }m\text{ }{{s}^{-2}}\] Coefficient of friction, \[\mu =0.5\] \[\therefore \]Frictional force \[F=\mu \times mg=0.5\times 35\times 10=175\text{ }N.\] Hence, the frictional force acting on body is 175 N.
