10\,\text{kg}

block rests on a rough incline of

30^{\circ}

with the horizontal. The coefficient of static friction between the block and the plane is

0.6

. The block remains at rest. What is the magnitude of the resultant contact force exerted by the plane on the block? (Take

g = 10\,\text{m s}^{-2}

.) a)
