WebMar 5, 2024 · The volume charge density of a sphere Charged sphere If a spherical conductor of radius R contains Q amount of charge inside its volume, then the formula for the volume charge density of the sphere is, \color {Blue}\rho=\frac {Q} {\frac {4} {3}\pi R^ {3}} ρ = 34πR3Q ……… (2) The volume charge density of a cylinder WebElectric Field: Sphere of Uniform Charge. The electric field of a sphere of uniform charge density and total charge charge Q can be obtained by applying Gauss' law. Considering a Gaussian surface in the form of a sphere at radius r > R, the electric field has the same magnitude at every point of the surface and is directed outward. tar book registration

WebNov 5, 2024 · We can also compare the surface charge densities on the two spheres: E1 = σ1 ϵ0 E2 = σ2 ϵ0 ∴ σ2 σ1 = E2 E1 = R1 R2 ∴ σ2 = σ1R1 R2 and we find that the charge density is higher on the smaller sphere. Thus, there are more charges per unit area on the smaller sphere than the bigger sphere. tar book apply
