A hollow, conducting sphere with an outer radius of 0.250 m and inner radius of 0.200 m has a uniform surface charge density of +6.50µC/m2. A charge of -5.00 µC is now introduced into the cavity inside the sphere.

(a) What is the new charge density on the outside of the sphere?

(b) Calculate the strength of the electric field outside the sphere.

(c) What is the electric flux through a spherical surface just outside the inner surface of the sphere?
