Notes – 22.5-22.6 Circular Motion in a Magnetic Field Lines and Crossed E and B Fields
1. Motion of a Charged Particle Moving Perpendicular to a Uniform Magnetic Field
A. Determine the direction of the force and path of the charged particle.
B
+q
v
B. Determine the velocity of the charged particle.
C. Determine the radius of the charged particle.
D. Determine the period and frequency.
2. Crossed E & B Fields
A proton with just the right velocity will pass straight through the apparatus
shown below from left to right that has crossed E and B fields that are
perpendicular to each other. The electric charges on the upper and lower plates
are shown.
