A block of mass \( 2 \mathrm{~kg} \) 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 \( [ \) IIT 1980; \( \mathbf{J} \& \mathrm{~K} \) CET 2004]
(a) \( 9.8 \mathrm{~N} \)
(b) \( 0.7 \times 9.8 \times \sqrt{3} \mathrm{~N} \)
(c) \( 9.8 \times \sqrt{3} \mathrm{~N} \)
(d) \( 0.8 \times 9.8 \mathrm{~N} \)
