In a mass spectrometer, the electric field between the plates of the velocity selector is 2 x 105 V/m, and the magnetic field is 2.0 T. You are trying to find the mass of a new singly charged positive ion. You discover that a stream these ions, after passing through the velocity selector, moves in a circular path with radius 30.0 cm in the magnetic field. (a) What is the speed of these ions just after passing through the velocity selector
