Parallel Plates: Two Large Conducting Parallel Plates a and B

question 37

Multiple Choice

Parallel plates: Two large conducting parallel plates A and B are separated by 2.4 m. A uniform field of 1500 V/m, in the positive x-direction, is produced by charges on the plates. The center plane at x = 0.00 m is an equipotential surface on which V = 0. An electron is projected from x = 0.00 m, with an initial velocity of 1.0 × 107 m/s perpendicular to the plates in the positive x-direction, as shown in the figure. What is the kinetic energy of the electron as it reaches plate A? (e = 1.60 × 10-19 C, mel = 9.11 × 10-31 kg) Parallel plates: Two large conducting parallel plates A and B are separated by 2.4 m.
