A solid metal sphere of radius a = 1.30 cm is surrounded by a concentric spherical metal shell of inner radius b = 3.50 cm and outer radius c = 4.00 cm. The inner sphere has a net charge of Q1 = 4.70 µC, and the outer spherical shell has a net charge of Q2 = -8.30 µC.
What is the surface charge density, sb, on the inner surface of the outer spherical conductor?
What is the surface charge density, sc, on the outer surface of the outer spherical conductor?
