A potential difference of 120 V prevails between two infinite charged and parallel plates, distances of 3 cm. An electron initially at rest starts from the plate with the lowest potential and completely crosses the space between the two plates. (a) What is the modulus of the electric field? (b) What work will the electric force do on the electron? (c) What is the variation in potential crossed by the electron?
Ex 16. A potential difference of 120 V prevails between two infinite charged and parallel plates, distances of 3 cm. An electron initially at rest starts from the plate with the lowest potential and completely crosses the space between the two plates. (a) What is the modulus of the electric field? (b) What work will the electric force do on the electron? (c) What is the variation in potential crossed by the electron? (d) What is the change in the potential energy of the electron? (e) How would you modify your answers if the space between the plates were filled with water (K = 80)? (We assume that water does not interfere with the movement of the electron).
