A diagram of a block on a 30 degree incline.
Which diagram represents the forces acting on the block?
A free body diagram with three forces: a force vector northeast labeled F Subscript N Baseline, a force vector southeast labeled F Subscript f Baseline, and a force vector south labeled F Subscript g Baseline.
A free body diagram with three forces: a force vector northeast labeled F Subscript N Baseline, a force vector southeast labeled F Subscript f Baseline, and a force vector southwest labeled F Subscript g Baseline that is equal in magnitude but opposite in direction to the vector pointing northeast.
A free body diagram with three forces: a force vector north labeled F Subscript N Baseline, a force vector southeast labeled F Subscript f Baseline, and a force vector south labeled F Subscript g Baseline, which is equal in magnitude but opposite in direction the north vector.
A free body diagram with three forces: a force vector northeast labeled F Subscript N Baseline, a force vector northwest labeled F Subscript f Baseline, and a force vector south labeled F Subscript g Baseline.
