The electric potential in a certain region is represented by the graph shown below. What is the electric force vector on an positron that is at x = 1.30 cm and moving to the right? Express your answer in vector form. F = How is the electric field defined in terms of the variation of the potential at any location? How is the force on a charge related to the electric field in which the charge is situated? Did you take into consideration the sign of the charge?
