Problem Description
An electron moves at a speed of 3.0x107 m/s straight through a region of uniform magnetic field.
No deflection from this straight path is observed.
melectron = 9.1 × 10-3'kg
Jelectron = -1.6 × 10-1ºC
Instructions
In a neat and organized fashion, write out a solution which includes the following:
1. A sketch of the physical situation with all given physical quantities clearly labeled. If the
description above consists of an initial and final state, both of these states should be
represented in your sketch.
2. Draw a force diagram showing all of the forces exerted on the electron.
3. Determine the magnitude and direction of the B-field such that the electron travels in a
perfectly straight line. Clearly show all steps, starting from generalized equations. Explain your
mathematical work in words. Your explanation should cover both what you did and the thought
process behind why you did that.
