Consider a system of three point charges as indicated in the figure below, where an x-axis and y-axis are shown as reference in the system. The coordinates of these charges are given as follows: ?1(0,0), ?2(d,0), and ?3(d,d). The charges ?1 and ?3 are positive, whereas the charge ?2 is negative. a) Express the resultant force ?⃗ 3 exerted on ?3, in terms of ?1, ?2, ?3, and d, in unit vector notation. Show all vectors on the figure, and...
