1. The problem statement, all variables and given/known data An electron in electric & magnetic fields; E = 3.0x107 ex NC-1 B = 3.0 ez T has velocity v = 1.0x10^7 (2ex-ey) Calculate em force on the electron. 2. Relevant equations I'm using the Lorentz force law here. F = q(E + v X B) I have an example solution using vectors to evaluate direction | ex_______ey_______ez | | 2.0x107_ 1.0x107 __ 0 | | 0_______0________3.0 | 3. The attempt at a solution I think this has been posted as the solution to vXB,but then why is the E value 3.0 T there??? Could someone please ecplain why this is.
