The angle between the two short sides is 90°. The two short sides of the triangle have length a. Investigate the net force on the charge (q) in the lower right corner due to the other two charges (q, -q). As needed, assume a right-handed coordinate system shown below: (A) What is the magnitude of the net force on the charge in the lower right corner due to the other charges? Use symbols for the answer. (B) Make a sketch of the net force vector on the x-y axes below with the tail of the arrow at the origin. Label the angle with the x-axis. What quadrant does the vector lie in? Your picture should indicate the correct quadrant.
