Question

Shown in the figure below are concentric conducting sphere and conducting spherical shell that are connected by a conducting wire. The geometrical parameters displayed in the figure are given: a=5.67 cm, b=24.57 cm and c=27.3 cm. The system is charged by adding charge qa=12.125 nC to the core and charge qc=11.5 nC to the shell as shown. What is the potential difference V between the center of the spherical core and infinity?: V= V. Find how much work W needs to be done to bring a very small test charge q=0.37 nC from infinity all the way to the outer surface of the system: W= mJ. ("Very small test charge" here means that its addition to the system would not practically change the system charge.)

Step 1

Since the core and shell are connected by a conducting wire, the charges will redistribute until they reach equilibrium. The total charge of the system is the sum of the charges on the core and the shell: $Q_{total} = Q_a + Q_c = 12.125 \,\text{nC} + 11.5 Show more…
