current density in metallic homogeneous sphere

Web6 jul. 2024 · The solution I suggest below works for both a conductor sphere and an insulator sphere in which the charge is homogenously distributed with a volume … WebIt's a little hard to understand what you're saying in the second half, but I think you have the right idea -- If you view the cavity as actually being a region that has charge density $\rho$ and $-\rho$ (so they add up to 0, which is what it actually is), now you can view it as two whole dielectric spheres, which can each easily be solved separately with Gauss's Law. hans josephsohn

Nuclear attraction integrals in the homogeneously charged sphere …

Web12 apr. 2024 · We know that on the closed gaussian surface with spherically symmetric charge distribution Gauss Law states: q ε 0 = ∮ E → ⋅ d A → Outside of sphere: Logically, the charge outside of a sphere will be always on the Gaussian surface and it doesn't change, therefore the electric field outside of a sphere: E = q 4 π ε 0 r 2 Web12 sep. 2024 · The potential of the charged conducting sphere is the same as that of an equal point charge at its center. Strategy The potential on the surface is the same as that of a point charge at the center of the sphere, 12.5 cm away. (The radius of the sphere is 12.5 cm.) We can thus determine the excess charge using Equation 7.4.1 V = kq r. Solution WebOne good way to determine whether or not your problem has spherical symmetry is to look at the charge density function in spherical coordinates, ρ(r, θ, ϕ). If the charge density is … hans just job
