... back into an integral. d ¯ΦdR= d dR=14πR2 d dRdAOne of the recurring themes of electrostatics is d dR= −En. Use it. d ¯ΦdR=14πR2 d dRdA = −14πR2EndA = 0By ... position a distance d away from an infinite plane conductor held at zero potential. Using the methodof images, find:a. the surface charge density induced on the plane, and plot it;Jackson asks ... several regions: r < d and r′> r, r < d and r′< r, r > d and r′> r, and r > d and r′< r. When the smoke clears,we find:Φ(r, θ, φ) =3Q16πǫ0 d 3∞ℓ=0(Pℓ(1)...
