Electric and Magnetic Forces
In a laboratory experiment, there is a region containing both an electric and a magnetic field. The strength of the electric
field is 3 kV/m. The strength of the magnetic field is 0.5 T.
The fields act on a moving electron to produce no net force.
(a) Whist is the minimum speed v of the electron?
(b) Draw a picture. Clearly indicate the directions of E, B, and u.

Expert Solution

Given information

The strength of the electric field E = 3 kV/m = 3000 V/m

The strength of the magnetic field B = 0.5 T.

# speed of the electron has to be evaluated.

# The direction of the vectors E, B, and v needs to be drawn.

Write down an expression for the force experienced by an electron moving with a velocity, v, in a magnetic field B. By equating this expression to the force required to cause electrons to follow a circular path of radius, r, derive an expression for the ratio, (?⁄?) for an electron in terms of the magnetic field strength, the radius of the circular path and the accelerating potential, V.
