A small block of mass 0.1kg lies on a fixed inclined plane PQ which makes an angle x with horizontal.A horizontal force of 1N on the block through its center of mass as shown The block remains stationary if
x = 45
x > 45 and friction acts towards p
x > 45 and friction acts towards Q
x < 45 and friction acts towards Q

If I take g=10. sinx = cosx only when x=45.

If g=9.8. sinx < cos x. So to make it stationary I would need friction towards P.

okay. so g must be 10. other option should be the third one. if x>45. sinx>cosx. and for block to be stationary we need friction towards Q.

@Ishaan94 in the question it is said that g =10m/s^2 i forgot to mention

if g =10 m/s^{2} then there is no friction because it arises when there is any tendency of motion. but at x =\[45^{o}\] the net force is zero.

m*g*sin(x)= 1* cos (x)substituting the value of m and g will give x= 45
