Consider the following configuration of source charge: ^ d -9 -29 d /2 B A +29 In this diagram, let q = 10nC and the distance d = 1cm. a.) Sketch what you think the electric field at points A and B look like. b.) Find E at point A. Remember, this is a vector, so find the contributions from each charge and add them up vectorially. c.) Now, find E at point B d.) Say I place a test charge of 10nC at B. What is the magnitude of the force it experiences?
