Part 1: Figure 20.14 shows a positive charge q moving with a nonzero speed v. If the magnetic field is directed to the right, is the direction of the magnetic force (a) into the plane of the drawing, (b) out of the plane of the drawing, (c) to the left, or (d) is the magnetic force zero?

Part 2: If the particle stops, is the direction of the magnetic force (a) into the plane of the drawing, (b) out of the plane of the drawing, (c) to the left, or (d) is the magnetic force zero?
