SUMMARY

The discussion focuses on determining the components of the magnetic field acting on an electron with a velocity of 1.90 km/s in the positive x direction and an acceleration of 2.00 E12 m/s² in the positive z direction, influenced by a uniform electric field of 20.0 N/C in the positive z direction. The participant concludes that the magnetic field component in the x direction can be any value, while the relationship between the electric and magnetic fields is crucial for understanding the motion of the particle. The participant also expresses uncertainty about the circular motion assumption and the effects of the electric field on the magnetic field.

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?
