1. The problem statement, all variables and given/known data An electron has an initial velocity of 5 × 105 m/s in the x direction. It enters a uni- form electric field ~E = (440 N/C) ˆj which is in the y direction. The charge and mass of an electron are 1.6×10−19 C and 9.11×10−31 kg, respectively. Find the acceleration of the electron. Answer in units of m/s2. 2. Relevant equations F=eq F=ma 3. The attempt at a solution I tried using those two equations and coming up with a = Eq/m, but thats not the correct answer!
