A uniform magnetic field points out of the page. A charged particle is moving in the plane of this page. If that particle travels in a clockwise spiral of increasing radius, then a reasonable explanation for this motion is (a) that particle is positively charged and slowing down. (b) that particle is positively charged and speeding up. (c) that particle is negatively charged and slowing down. (d) that particle is negatively charged and speeding up.
