A magnetic field has a magnitude of 480 mT and an electric field has a magnitude of 2.10 x 10 N/C are oriented perpendicular to one another in order to form a velocity selector, with the magnetic field vertically up (out of the page). (a) With what speed will a charged particle pass straight through the velocity selector? (b) If the velocity of the charged particle is to be to the south (down on the page), what direction will the electric field need to point in the velocity selector? After having passed through the velocity selector the negative doubly ionized isotope, X², enters a mass spectrometer i.e., a region with a constant magnetic field with magnitude 680 mT also going up (out of the page) and still perpendicular to the direction of motion of the isotope. (c) If the diameter of the resulting circular motion is 8.50 mm then what is mass of the ionized isotope. Include a diagram of each situation.
