9. A particle with unknown (non-zero) charge q moves to the left with speed v. It enters a region with uniform electric field E directed downward and uniform magnetic field B directed out of the page. If the charged particle follows a straight line path to the left (as shown in the figure below) in moving through the region of perpendicular electric and magnetic fields, then the sign of the charge must be: Explain. [5] B (a) positive (+) (b) negative (-) (c) could be either (+) or (-) (d) neither, because a charged particle moving in a plane that is perpendicular to a magnetic field must execute circular motion
