1. The problem statement, all variables and given/known data 4 A long, straight wire carries a current of 25.0 A. An electron is fired parallel to this wire with a velocity of 250 km.s-1 in the same direction as the current, 2.00 cm from the wire. a) Find the magnitude and direction of the electron’s initial acceleration. b) What should the magnitude and direction of a uniform electric field be that will allow the electron to continue to travel parallel to the wire? 2. Relevant equations 3. The attempt at a solution B=kI/d B=2.5*10-4 T F=Bqv F=1*10-17N F=ma a=1.099*1012m/s2 E=F/q E=62.5N/c I'm relatively confident with my numerical answers although I would appreciate someone looking over my basic procedure. I run into trouble tying to explain the direction of the field. Were using conventional current (don't ask me why) and the best indication of the direction I can give is "at 900 away from the wire", thoughts??? Thanks.
