Angle of Electron Velocity Change: 8 Degrees

Then, use the equations of motion to find the final velocity and the angle it makes with the original velocity. In summary, the problem involves an electron being fired through deflection plates with a perpendicular electric field. The initial speed of the electron is given, and the goal is to find the angle of the electron's new velocity with the original velocity. To solve this, first calculate the acceleration due to the electric field, then determine the time the electron is in the field, and finally use the equations of motion to find the final velocity and angle.

Homework Statement


An electron is fired through a pair of deflection plates, which produce a 2.00 cm long region with an electric field of 4000 N/C perpendicular to the electron's initial velocity. If the initial speed of the electron is 1.00 × 107 m/s, what angle will its new velocity make with the direction of the original velocity?*



Homework Equations





The Attempt at a Solution



I know it's 8 degrees (multiple choice question) I just don't even know where to start with this. I imagine I'm going to have to use an inverse tan eventually.
