WebFigure 6.34 Polarization of a metallic sphere by an external point charge + q + q.The near side of the metal has an opposite surface charge compared to the far side of the metal. … WebWe have just seen that the electrical potential at the surface of an isolated, charged conducting sphere of radius R is V = 1 4πrϵ0 q R. V = 1 4 π r ϵ 0 q R. Now, the spheres are connected by a conductor and are therefore at the same potential; hence 1 4πrϵ0 q1 R1 = 1 4πrϵ0 q2 R2, 1 4 π r ϵ 0 q 1 R 1 = 1 4 π r ϵ 0 q 2 R 2, and

WebFeb 7, 2012 · I presume that you mean ρ = ρ 0 (r/R) is the volume charge density for a sphere of radius, R, where ρ 0 is the volume charge density at the surface of the sphere. The volume element is dV = 4 π r 2 dr. So that dq = 4 π r 2 (ρ)dr = 4 π r 2 (ρ 0 /R)r dr . 4, π, ρ 0, and R are all constants. Integrate that over the entire sphere. → r goes from 0 to R .
