Problem
A student draws a free-body diagram for a wooden block that rests motionless on a horizontal tabletop. The diagram shows four arrows originating at the dot: (1) a downward arrow labeled "weight," (2) an upward arrow labeled "normal," (3) a leftward arrow labeled "static friction," and (4) a second downward arrow labeled "force of the block on the table." Identify the error in the student’s diagram and briefly explain why it is incorrect.
