Question
Chapter 28, Problem 001 A proton traveling at 23.8° with respect to the direction of a magnetic field of strength 1.98 mT experiences a magnetic force of 9.59 × 10-¹7 N. Calculate (a) the proton's speed and (b) its kinetic energy in electron- volts. Chapter 28, Problem 009 In the figure, an electron accelerated from rest through potential difference V₁=1.06 kV enters the gap between two parallel plates having separation d = 24.5 mm and potential difference V₂= 99.1 V. The lower plate is at the lower potential. Neglect fringing and 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? [₁}v₂
