The figure shows two nonconducting spherical shells fixed in place on an x axis. Shell 1 has uniform surface charge density 3.50 μC/m2 ?
The figure shows two nonconducting spherical shells fixed in place on an x axis. Shell 1 has uniform surface charge density 3.50 μC/m2 on its outer surface and radius 0.100 cm, and shell 2 has uniform surface charge density -2.50 μC/m2 on its outer surface and radius 2.20 cm; the centers are separated by L= 10.0 cm. Other than at x = ∞, where on the x axis is the net electric field equal to zero?
