A small block of mass of 0.1 kg lies on fixed inclined plane PQ which makes an angle $$\theta$$ 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 $$m/s^2$$)

A

$$\theta = 45^\circ$$

B

$$\theta > 45^\circ$$ and frictionalforce acts on the block towards P.

C

$$\theta > 45^\circ$$ and frictional force acts on the block towards Q.

D

$$\theta < 45^\circ$$ and frictional force acts on the block towards Q.
