motion in a electric field |
Hi there,
having some problems with homework, yes homework. I know this is extremely
simple but I can't quite get it.
Basically, whats the motion of a positive test charge in a E field given by
E = Eocos(wt) i , where initial velocity is v(0) = {Vx,o, 0, Vz,o}
pg

What have you done so far? Consider this:
The only force is from the E field, and that's in the x direction. Any
speeds in other directions will be constant. In the x direction, apply
f=ma. You know the charge, you know the E field, so you can figure the
force. Given the mass, you can then get the acceleration and integrate
twice for the x motion.

This is not a service for solving homework problems.

You can simplify your work by noticing that the
double integral of E cos wt is E(-cos wt)/w^2.
