Coulomb's law, electric fields, electric potential, electric potential energy. 1. Two charges are positioned (fixed) at the corners of a square as shown. In this case, q refers to a magnitude of charge. The sign of the charge is indicated on the drawing. (a) What is the direction of the electric field at the point marked x ? (Choose from one of the 4 options shown.) (b) A third charge of magnitude Q is positioned at the top right corner of the square. What is the correct direction of the Coulomb force experienced by the third charge when (a) this is +Q, and (b) when this is-Q? (Choose from one of the 4 options shown.) D D T T -q -9 B B
