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 centre of mass as shown in the figure. The block remains stationary if ( take `g=10 m//s^(2))`

A

`0=45^@`

B

`theta lt 45^@ an a frictional force acts on the block towards P.

C

`theta gt 45^@` and a frictional force acts on the block towards Q.

D

`theta lt 45^@` and a frictional force acts on the block towards Q.
