An infinite uniform line charge of 2μC is located on Z axis . Find electric field E at point P(1,2,3) in Cartesian coordinates .

A charge cloud is distributed through a spherical volume. The charge is non-uniformly distributed with a distribution ρ_v = ρ_or C/m³, where ρ_o = 10^–7 and r is the distance from the centre of the sphere. The total charge (in mC) in a sphere of radius r_o = 10 m is?

Let D = 8ρsinϕ a_ρ + 4ρ cosϕ a_ϕ C/m². Find the volume charge density at P(2.6, 38°, – 6.1) and also calculate how much charge is located inside the region defined by 0 < ρ < 1.8, 20° < ϕ < 70°, 2.4 < z < 3.1?

A point charge of 5 nC is located at origin. If V=2V at B(0, 6, –8), then the potential at A(–3, 2, 6) is
