The point charges in the figure below are located at the corners of an equilateral triangle 22.0 cm on a side. (Assume that the +x-axis is to the right and the +y-axis is up along the page.) qc (a) Find the electric field (magnitude in N/C and direction in degrees counterclockwise from the +x-axis) at the center of the triangular configuration of charges in the figure, given that q = +3.50 nc, q = -8.50 nC, and q = +5.50 nc. magnitude direction N/C counterclockwise from the +x-axis (b) Is there any combination of charges, other than 9 = 9 = 9 that will produce a zero strength electric field at the center of the triangular configuration? Yes No
