Red blood cells often become charged and can be treated as point charges. Healthy red blood cells are negatively charged, but unhealthy cells (due to the presence of a bacteria, for example) can become positively charged. In the figure, three red blood cells are oriented such that they are locate on the corners of an equilateral triangle. The red blood cell charged are A = 1.90 pC, B = 7.30 pC, and C = -4.10 pC. Given these charges, what would the magnitude and direction of the electric field be at cell A?  a) magnitude = ____ N/C b) direction = ____ ° counterclockwise from the +x-axis
