Two uniform spherical charge distributions (see figure below) each have a total charge of 74.3 mC and radius R = 15.2 cm. Their center-to-center distance is 37.50 cm. Find the magnitude of the electric field at point B, 7.50 cm from the center of one sphere and 30.0 cm from the center of the other sphere. N/C R = 15.2 cm R = 15.2 cm B 37.50 cm 30.0 cm 7.5 cm
