Question : 14 of 60

Marks: +1, -0

A small block of mass 0.1 kg lies on a fixed inclined plane PQ which makes an angle θ with the horizontal. A horizontal force of 1 N acts on the block through its centre of mass as shown in the figure. The block remains stationary if (take g = 10 m∕s2)

[JEE Adv 2012 P1]

θ = 45°
θ > 45° and a frictional force acts on the block towards P.
θ > 45° and a frictional force acts on the block towards Q.
θ < 45° and a frictional force acts on the block towards Q.
