59. The distance from Qto Pis 5a, and the distance from qto Pis 3a. Therefore, the magnitudes of the individual electric fields are, using Eq. 22-3 (writing 1/4πε0= k), GGEkQaEkqaQq==25922,.We note that GEqis along the yaxis (directed towards ±yin accordance with the sign of q), and GEQhas xand ycomponents, with GGEEQxQ=±45and GGQyQ35(signs corresponding to the sign of Q). Consequently, we can write the addition of components
