a horizontal force of 50 N is required to keep the block moving with constant velocity . The ratio coefficient of static and kinetic friction is ,
A block rests on a rough inclined plane making an angle of 30 degrees with the horizontal. The coefficient of static friction between the block and the plane is 0.8. If the frictional force on the block is 10 N, the mass of the block in (kg) is: (Take g = 10 m/second square)
