Question #1. Protons are accelerated from rest through a
potential difference of 2.93 kV and enter a velocity filter,
consisting of a parallel-plate capacitor and a magnetic field (into
the page), as shown.
The E-field between the capacitor plates is 3.30×105 N/C. What B-field is required so that the protons are not deflected?
Question #2. A 6.45 µC particle moves in the x-y plane, through a region of space where an electric field of magnitude 1230 N/C points in the positive x direction, and a magnetic field of magnitude 1.00 T points in the positive z direction. If the net force acting on the particle is 6.38×10-3 N in the positive x direction, find the particle's speed.
