1. Two point charges 9 and 92 are located a distance L from the origin, along the x and y axes, respectively (see Fig. 1 below). a. Calculate the magnitude of the electrostatic force between the two charges. L = b. Assuming now that the charges are fixed in place, when q = 92 electric field E (magnitude and direction) at the origin. A (92) L (91) +q, calculate the 8)
