Uniform magnetic field and electric field

Click For Summary
SUMMARY

The discussion focuses on determining the period of a charged particle moving in a uniform electric field and magnetic field, both oriented along the x-axis. The participant correctly identifies that in the absence of an electric field, the period can be calculated using the formula T = 2π(m/qB). However, they express uncertainty about how to incorporate the electric field into this calculation. The conversation highlights the need to clarify the relationship between the electric and magnetic forces acting on the particle and how to derive the velocity after a specified number of revolutions.

PREREQUISITES
  • Understanding of Lorentz force law: F = q(E + v × B)
  • Knowledge of circular motion and period calculation: T = 2π(m/qB)

Homework Statement


How would you find the period of a charged particle in an uniform electric and magnetic field?
The charged particle has velocity that is perpendicular to the magnetic and electric field (which are directed in the x-axis).

Homework Equations


F=q(E+vxB)


The Attempt at a Solution


In the absence of an electric field, I see that the period is given by T=2pi(m/qB). Not sure how I can find it when an electric field is present.

Hey, when you say period, do you mean that the particle is orbiting something?
 
I misunderstood the question, but I need to find the magnitude of the velocity after 'c' revolutions.
 
What does "directed in the x-axis" mean? If you were to write the three Cartesian components of, say, the electric field vector, what might it look like?
 
I am lost with this question, but to go about finding the velocity at time t I think it's v=q/m (integral)[E+vxB]dt, it's just the limits of integration I'm not able to find.

Thanks for replying.
