(b) Repeat your calculation for a proton having the same velocity. An electron moves through a uniform Magnetic field given by () +Bij. At a particular instant, the electron has velocity () m/s=+vij and the Magnetic force acting on it is()19 10 N. k Find Bx. should be 10 14 N Ch. 28 Magnetic Fields HRW10 End-of- Chapter problems Copyright 2014 John Wiley & Sons, Inc.

assume that the electron’s velocity vector is perpendicular to the electric field vector between the plates. In unit-vector notation, what uniform magnetic field allows the electron to travel in a straight line in the gap? 28.23 What uniform magnetic field, applied perpendicular to a beam of electrons moving at 1.30 × 106 m/s, is required to
