Question
A region has a uniform electric field, E, that is pointing in the upward (+j direction) and a uniform magnetic field, B, traveling perpendicular to
A region has a uniform electric field, E, that is pointing in the upward (+j direction) and a uniform magnetic field, B, traveling perpendicular to this E field. A proton, q, is moving into this "crossed fields" region in the positive x direction (+i direction).
a) [6 points] What is the magnitude and direction of the electric force on the particle? b) [6 points] What is the magnitude of the magnetic force on the particle? c) [6 points] What direction does the magnetic FORCE have to point to allow the proton to travel through undeflected?
d) [6 points] What direction would the magnetic FIELD have to point to yield a magnetic force that allows a proton to pass through undeflected? How do you find this direction? e) [6 points] Find an equation for the velocity for a particle to travel through undeflected (show all work)
