Two conducting spherical shells are concentric. One sphere has inner radius 3.0cm, and outer radius 4.0cm while the second shell has inner radius 6.0cm and outer radius 8.0cm. The smaller sphere has charge of 2.0 nC and larger sphere has a charge of -6.0 nC. How much charge is on the inner and outer surfaces of each sphere? At what potential is each sphere? If two spheres were then connected ...I found an answer from www.quora.comIf two concentric spherical shells have charges of [math]q_1[/math ...The electric field is related to the surface charge density as E=Sigma/epsilon ... If two concentric spherical shells have charges of and , having a radius of and ... electric field outside the outer sphere is dependent on the charge of the inner sphere. ... A solid conducting sphere ...

A spherical capacitor has an inner sphere of radius 12 cm and outer sphere of radius 13 cm. The outer sphere is earthed and the inner sphere is given a charge of 2.5 μC. The space between the concentric spheres is filled with liquid of dielectric constant 32. (a) Determine the capacitance of the capacitor. (b) What is the potential of the ...
