A block of mass \( 2 \mathrm{~kg} \) rests on a rough inclined plane making an angle of \( 30^{0} \) with the horizontal. The coefficient of static friction between the block and the plane is 0.7 . The frictional force on the block is :
(a) \( 9.8 \mathrm{~N} \)
(b) \( 0.7 \times 9.8 \sqrt{3} \mathrm{~N} \)
(c) \( 9.8 \times 7 \mathrm{~N} \)
(d) \( 0.8 \times 9.8 \mathrm{~N} \)
