A small block of mass of 0.1 kg lies on a fixed inclined plane PQ which makes an angle q with the horizontal. A horizontal force of 1 N acts on the block through its center of mass as shown in the figure. The block remains stationary if (take g = 10 m/s2).
Answer
(C) q > 45° and a frictional force acts on the block towards Q .
