1. An electron moves north at a velocity of 1.5 x 104 m/s and has a magnetic force of 2.2 x 10-14 N exerted on it. If the magnetic field points upward, what is the magnitude of the magnetic field? Use 1.60 x 10-19 C for the magnitude of the charge of an electron. Please show step by step on how you got the answer.
2. The maximum current supplied by a generator to a 35 Ω circuit is 8.2 A. What is the rms potential difference?
