For the configuration shown in the figure below, suppose a = 5.00 cm, b = 20.0 cm, and c = 25.0 cm. Furthermore, suppose the electric field at a point 12.0 cm from the center is measured to be 3.80 x 10³ N/C radially inward and the electric field at a point 50.0 cm from the center is of magnitude 236 N/C and points radially outward. From this information, find the following. (Include the sign of the charge in your answer.) Insulator Conductor
