Unformatted text preview: q 2 (where x > d ), ~ E 1 points leFtward and ~ E 2 points rightward so the net feld in this range is ~ E net = ~ E 2 ~ E 1 in the i direction . Although  q 1  > q 2 there is the possibility oF ~ E net = 0 since these points are closer to q 2 than to q 1 . Thus, we look For the zero net feld point in the x > d region: ~ E 1 = ~ E 2 1 4  q 1  x 2 = 1 4 q 2 ( x d ) 2 which leads to x d x = r q 2  q 1  = r 1 2 . ThereFore, x = d 2 2 1 = 6 . 8 m specifes the position where ~ E net = 0 ....
