The figure shows two nonconducting spherical shells fixed in place on an x axis. Shell 1 has uniform surface charge density 4.50 µC/m? on its outer surface and radius 0.200 cm, and shell 2 has uniform surface charge density -1.00 µC/m? on its outer surface and radius 1.60 cm; the centers are separated by L= 8.00 cm. Other than at x = 0, where on the x axis is the net electric field equal to zero? Shell Shell 2 L Number Units
