| Physics help- Magnetic Fields?
I really don't understand this. Could somebody please tell me which formulas to use to solve this problem, and why? I'm not very good at visualization and I can't even begin to imagine how to solve this problem. I've read to book, but to no avail. Thanks.
"A proton moves perpendicularly to a uniform magnetic field at 5.0 107 m/s and exhibits an acceleration of 2.0 1013 m/s2 in the +x-direction when its velocity is in the +z-direction. Determine the magnitude and direction of the field." |
