Your answer is partially correct. The figure shows two nonconducting spherical shells fixed in place. Shell 1 has uniform surface charge density +6.5 C/m on its outer surface and radius 4.3 cm; shell 2 has uniform surface charge density +4.1 C/m on its outer surface and radius 1.5 cm; the shell centers are separated by L = 10.0 cm. What is the x-component (with sign) of the net electric field at x = 2.1 cm? Shell Shell 2 D Number -1320 Units N/C x
