Question 1 of 4
HARDA block of mass 5 kg is placed on a rough inclined plane making an angle of 37° with the horizontal. The coefficient of static friction between the block and the plane is 0.5. What minimum force (in N) applied horizontally can prevent the block from sliding down? (Take g = 10 m/s², sin37° = 0.6, cos37° = 0.8)
