An electron is moving with a speed of 3*10^6 m/s. What are the directions (NE, N, NW,..., In the screen, out of the screen, zero magnitude) of the electric and magnetic field. What is the magnitude of the electric and magnetic field?
moves this direction 3e6 / / angle = 60 degrees electron-------------------------Observation location, d = 3e-10
for field direction the right hand rule is applicable
The Attempt at a Solution
Efield is similar to a Efield from a electric circuit, applying the right hand rule in the opposite direction of the movement of the electron gives out of the screen.
Mfield is, at a speratic guess (using a left hand rule i think) is East
|E|=1/4pi epsilon naught * chargeOfelectron/d^2
