Two capacitor plates are equally and oppositely charged

Question

Two capacitor plates are equally and oppositely charged. They are separated by 1.4cm. An electron is released from rest at the surface of the negative plate and, at the same time, a proton is released from rest at the surface of the positive plate.

Where do the proton and electron pass each other? Give your answer as a distance from the positive plate.

Answer 1

1. Two capacitor plates are equally and oppositely charged. They are separated by 6.30 cm. An electron is released from rest at the surface of the negative plate and, at the same time, a proton is released from rest at the surface of the positive plate. Where do the electron and proton pass each other? Give your answer as a distance from the positive plate. What is the angle of the electric field at the position indicated by the dot? Measure the angle cw from +x-axis.
