Question

The figure below shows two nonconducting spherical shells fixed in place. Shell 1 has uniform surface charge density +6.0 µC/m2 on its outer surface and radius 3.0 cm. Shell 2 has uniform surface charge density +3.7 µC/m2 on its outer surface and radius 2.0 cm. The shell centers are separated by L = 12 cm. What are the magnitude and direction of the net electric field at x = 2.0 cm?

Answer 1

Determine the net electric field at the point x- 2cm, due to the both shell Use Gauslaw to determine the electric field as follows Here, q is the charge enclosed by the Gaussi an surface, A surface area. Eelectric fiel d due shell one is zero, Because there is no charge inside the Gaussian surface at 2cm Electric field due to another shell is (3.7x10) 4T(0.02) AT(0.12-0.02 8.85x10-12) (3.7x10*) (002)) (0.12-0.025 (8.85x10-12) 1.672 x104 NIC this is towards negative x-axis.Left si de Therefore, the net electric field is |-1.672x 104 NC
