An Electron Is Fired Through the Space Between Two Oppositely

An electron is fired through the space between two oppositely charged, parallel plates. The plates form 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 relative to the direction of the original velocity?

A) 14^°
B) 8.0^°
C) 5.5^°
D) 4.6^°
E) 1.4^°
