The drawing shows the circular paths of an electron and a proton. These particles have the same charge magnitudes, but the proton is more massive. They travel at the same speed in a uniform magnetic field , which is directed into the page everywhere. Which particle follows the larger circle, and does it travel clockwise or counterclockwise?
__________Particle __________Direction of Travel
(a) ........... Electron ....................... Clockwise
(b) .......... Electron .............. Counterclockwise
(c) ............ Proton ....................... Clockwise
(d) ............ Proton ............. Counterclockwise |
