Concentric with this sphere is a charged, conducting hollow sphere with inner and outer radii of b = 10 cm and c = 14 cm and total charge of -4 {eq}\mu C {/eq}. Find: a. the charge contained ... Question 20. Two charged conducting spheres of radii a and b are connected to each other by a wire. What is the ratio of electric fields at the surfaces of the two spheres? Use the result obtained to explain why charge density on the sharp and pointed ends of a conductor is higher than on its flatter porti

Two . neutral. identical metallic spheres, separated by 1.0 m (center to center distance), are connected by a very thin conducting wire. An 8.0 C charge is placed on one of µ the spheres. Then, after a long time, the two spheres are disconnected from each other. Find the magnitude of the electrostatic force of one sphere on the other after ... 4.10 Two concentric conducting spheres of inner and outer radii a and b, respectively, carry charges ±Q. The empty space between the spheres is half-ﬁlled by a hemispherical shell of dielectric (of dielectric constant / 00, as shown in the ﬁgure. a-Q +Q b a) Find the electric ﬁeld everywhere between the spheres. This is a somewhat ... You misunderstand the problem. The two shells are concentric, the radii are given, r1 and r2. The potential is given for both spheres; V1 and V2 . The problem asks the potential at distance ro=(r1+r2)/2 from the common centre of the spheres. In the centre, the potential is the same as on the inner sphere, that is V1.
