An electron is moving in a plane that also contains a long straight current-carrying wire. The electron is heading at a 45° angle toward the wire, with a speed of 3.8 106 m/s, when it is 43 cm away. The electron reaches only as close as 1 cm, before being repelled away, always moving in the same plane. What is the current in the wire?
I could picture it well but i have no idea how to solve this problem. All i knwo is that its velocity should be constant because its in the plane perpendicular to the magnetic field and the force i think.. Can anyone tell me how to do it or give me any hints that would help me think better.
Your help would be greatly appreciated!
