Find electric field from potential
WebApr 12, 2024 · In this case a spherical surface is very convenient since because of the symmetry of the electric field, the field vectors will always be parallel to the normal vectors of the surface. Which means that (1) ∮ E → ⋅ d A → = E ∗ 4 π ∗ r 2 WebQ6) For each of the following potential distributions, find the electric field intensity, the volume charge density, and the energy required to move 2 μ c from A (3, 4, 5) to B (6, 8, 5): a. V = 2 x 2 + 4 y 2 b. V = 10 ρ 2 sin φ + 6 ρ z c. V = 5 r 2 cos θ sin φ
