Problem:
Shown is an arrangement of two conducting shells and a conducting sphere.
Initially the conducting sphere is charged to +4 C and the two conducting shells have zero net charge. The regions between the objects are free space.
a) What is the total charge in the inner wall of shell B?
b) What is the total charge on the outer wall of shell B?
c) What is the total charge in the inner wall of shell A?
d) What is the total charge on the outer wall of shell A?
Shell B is moved till the outer wall of shell B touches the inner wall of shell A and then moved back to its original position. Shell B and the inner sphere never touch.
e) What is the charge on the sphere?
f) What is the total charge in the inner wall of shell B?
g) What is the total charge on the outer wall of shell B?
h) What is the total charge in the inner wall of shell A?
i) What is the total charge on the outer wall of shell A?
