Imagine an electron brought from rest from infinity to a point, P, located at a distance, 5 cm, from a fixed charge, q. The work required for this to be arranged is 90 eV. a. What is the electric potential at point P? b. What is the value of charge q? c. Now, with charge q held in place, the electron is released from rest. What is the electron's speed when it is 10 cm away from the charge q?
