1. The problem statement, all variables and given/known data 1. What is the magnitude and direction of the electric field at point Z in the diagram? q = - 2.0 x 10-5 C q = + 8.0 x 10-6 C 60 cm 30 cm X Y Z 2. An electron is released from rest adjacent to the negative plate in a parallel plate apparatus. A potential difference of 500 V is maintained between the plates, and they are in a vacuum. With what speed does the electron collide with the positive plate? 2. Relevant equations Electric Field type questions 3. The attempt at a solution I attempted them but I don't remember how to do them, it was a long time. I need some assistance. Your help will be greatly appreciated. Thank you.
