The magnitude of the electric potential
A small charged sphere of radius a=1.10 cm is suspended by a nylon thread inside a larger neutral, conducting sphere. The larger sphere has an interior radius b=4.70 cm and is Δ=0.5 cm thick. The charge on the small sphere is q=0.90 nC. The two spheres are concentric and insulated from their surroundings. For the following ...continues
