A uniform electric field E = 91 × 10 –6 V/m is created between two parallel, charged plates as shown in figure. An electron enters the field symmetrically between the plates with a speed v 0 = 4 × 10 3 m/s. The length of each plate is λ = 1m. Find the angle of deviation of the path of the electron as it comes out of the field. (Mass of the electron is m = 9.1 × 10 –31 kg and its charge is e = –1.6 × 10 –19 C).
