Q3
A plane surface is inclined at an angle of 600 with the vertical. A body of mass 10 kg is uniformly accelerating, along the inclined plane surface. If the value of coefficient of friction μK, between the body and the inclined surface is 0.2, calculate the resultant force of friction acting between the surfaces in contact. (Take g=10ms2)
