A Solid, Conducting Sphere of Radius a Carries an Excess $\mu$

question 9

Multiple Choice

A solid, conducting sphere of radius a carries an excess charge of +6 µC. This sphere is located at the center of a hollow, conducting sphere with an inner radius of b and an outer radius of c as shown. The hollow sphere also carries a total excess charge of +6 µC.
-Determine the excess charge on the inner surface of the outer sphere (a distance b from the center of the system) .

• A)zero coulombs
• B)-6 \(\mu\)C
• C)+6 \(\mu\)C
• D)+12 \(\mu\)C
• E)-12 \(\mu\)C
