Question

Multiple correct answers type
A small block of mass of 0.1 kg lies on a fixed inclined plane PQ which makes an angle $\theta$ with the horizontal. A horizontal force of 1N acts on the block through its center of mass as shown in Fig. The block remains stationary if ( take g = 10 $m{s}^{-2}$)
a. $\theta ={45}^0$
b. $\theta >{45}^0$ and a frictional force acts on the block towards P
c. $\theta >{45}^0$ and the frictional force acts on the block towards Q
