Question

The figure

The figure below shows four choices for the direction of a force of magnitude F to be applied to a block on an inclined plane. The directions are either horizontal or vertical. (For choices a and b, the force is not enough to lift the block off the plane.) Rank the choices according to the magnitude of the normal force on the block from the plane, greatest first (use only the symbols > or =, for example c>b>a>d).

Explanation / Answer

d>c>a>b

explanation......

for d , N = m*g*cos(30) + d*cos(30)

for c ,   N = m*g*cos(30) + d*cos(60)

for a ,   N = m*g*cos(30) - a*cos(60)

for b,   N = m*g*cos(30) - b*cos(30)
