A beam of electrons is undeflected when passing through perpendicular electric and magnetic fields of magnitude 8.8E3 N/C and 3.5E-3 T, respectively.

a) What is the relationship between the electric and magnetic forces acting on these electrons?

b) Calculate the speed of the electrons.

c) Suppose a beam of alpha particles was used instead? By what factor would the speed change?

You can use either electric or magnetic fields to steer moving charges. Suppose you have a beam of electrons moving in the xdirection with speed 1.0×107 m/s, and you want them to turn 30° to their right in a distance of 1.00 cm.(a) [2 pts.] One way to turn the electrons is to run them between two charged plates that are 1.00 cm wide. There will be a uniform electric field between the plates. What direction does the electric field...

A beam of electrons is accelerated through a potential difference of 10 kV before entering a velocity selector. If the B-field of the velocity selector has a value of .010 T, what value of the E-field is required if the particles are to be undeflected? I have the answer. It is 5.9 x 10^5 V/m. Please thouroughly explain how to get to this answer and what undeflected means.
