3.0\,\text{kg}

block rests on a rough plane inclined at

40^{\circ}

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

0.50

. A force

F

acts normal to the plane, pressing the block against the surface. Determine the minimum value of

F

required so that the block remains at rest. (Take

g = 9.8\,\text{m\,s}^{-2}
