A body of mass 10kg rests on a rough inclined plane whose angle of tilt \(\theta\) is variable. \(\theta\) is gradually increased until the body starts to slide down the plane at 30^o. The coefficient of limiting friction between the body and the plane

0.30

0.50

0.58

0.87

Correct answer is C

n = tan 30 = 0.58
