A block of mass 2 kg rests on a rough inclined plane making an angle of

30^\circ

with the horizontal. The coefficient of static friction between the block and the plane is 0.7. The frictional force on the block is (1) 9.8 N (2)

0.7 \times 9.8 \times \sqrt{3}

N (3)

9.8 \times \sqrt{3}

N (4)

0.7 \times 9.8
