Homework Statement
An electron has a velocity of 1.90 km/s (in the positive x direction) and an acceleration of 2.00 E12 m/s^2 (in the positive z direction) in uniform electric and magnetic fields. If the electric field has a magnitude of strength of 20.0 N/C (in the positive z direction), determine the following components of the magnetic field. If a component cannot be determined, enter 'any value' or 'not applicable' - whichever is most appropriate.
B(x direction):
B(y direction):
B(z direction):
Homework Equations
F=qvBsin(theta)
F=ILB
sum of forces=(mass)(centripetal acceleration)
There may be some others as well.
The Attempt at a Solution
Well, I know that B(x direction) can be any value. I am assuming that the motion of the particle is circular, and it is in the z-plane. Is this right?
I really don't even know where to start on this, and I have to submit it to my teacher by midnight, and the book doesn't explain anything like this. How does the electric field affect the magnetic field?
