WebA metal sphere with radius r_a is supported on an insulating stand at the center of a hollow, metal, spherical shell with radius r_b. There is charge +q on the inner sphere and charge -q on the outer spherical shell. (a) Calculate the potential V(r) for (i) r r_b. (Hint: The net potential is the sum of the potentials due to the individual spheres.) Web1 day ago · We postulated that an emulsion-oriented assembly strategy—in which oil droplets interact with mesoporous silica nanoparticles (MSNs) to form double-spherical structures, and subsequently direct ...

WebMar 5, 2024 · Inside the sphere, the field is zero and therefore the potential is uniform and is equal to the potential at the surface, which is − G M / a. The reader should draw a graph of the potential as a function of distance from centre of the sphere. There is a discontinuity in the slope of the potential (and hence in the field) at the surface.
