An electron moves through an electric field such that it slows down, losing 190J of kinetic energy. The change in potential experienced by the charge is -8V. A. What is the magnitude of the electron? B. If the positive charge of the double the magnitude of the first charge moved between the same two points in the field, determine the change in electric potential and the change in electric potential energy.(please help, I have time limit to answer this please make the solution clear)

Directions: Choose the letter of the correct answer. Write “E" if you think the correct answer is not part of the options. 1. Electron and proton are placed at two different locations (one charge at each location). The locations have the same electric potential. Do these charges have the same electric potential energy? a Yes, if the electric potentials at the two locations are the same, the electric potential energies are also the same, regardless of the sign and magnitude of the charges placed at these locations. b. No, because the electric potential energy EPE at a given location depends on the charge placed at that location as well as the electric potential V. c. Both A and B d. None of the above 2.
