22. A block rests on a rough inclined plane making an angle of 30° with the horizontalThe coefficient of static friction between the block and the plane is 0.8. If the frictionalforce on the block is 10 N, then the mass (in kg) of the block is (Take g-10 m/s)(A) 2.0(B) 4.0(D) 2.5

Answer»

F=mg×sinθ

10=m×10×sin30°

m=2kg
