Suppose you want to dertermine the electrical field in acertain region of space. You have a small object of knowncharge and an instrument that measures the magnitude and directionof the force exerted on the object by the electrical field. (a) The object has a charge of +20.0uC and the instrumentindicates the electrical force exerted on it is 40.0uN, dueeast. What are the magnitude and direction of the electricalfield? (b) What are the magnitude and direction of the electrical field if the object has a charge of -10.0uC and the instrument indicates that the force is20.0uN, due west.
