Question

(8c23p69) A thin, metallic, spherical shell of radius a = 7.0 cm has a charge qa = 5.00×10-6 C. Concentric with it is another thin, metallic, spherical shell of radius b = 18.90 cm and charge qb = 5.00×10-6 C.

Find the electric field at radial points r where r = 0.0 cm.

Find the electric field at radial points r where r = 13.0 cm.

Find the electric field at radial points r where r = 28.4 cm.

Discuss the criterion one would use to determine how the charges are distributed on the inner and outer surface of the shells. What is the charge on the outer surface of the outer shell?

For Conductor

Charge always resides on the outer surface of the conductor.
if there is a cavity inside the conductor having no charge then the charge will always reside only
on the outer surface of the conductor.
