A uniform volume charge density of 0.2 μC / m^3 is present throughout the spherical shell extending from r=3  cm to r=5  cm. If ρv=0 elsewhere, find (a) the total charge present throughout the shell, and (b) r1 if half the total charge is located in the region 3  cm<r<r1.

If volume charge density is given as ρv=(cosω t) / r^2C / m^2 in spherical coordinates, find 𝐉. It is reasonable to assume that 𝐉 is not a function of θ or ϕ.

SOLVED: The volume charge density inside and outside a spherical charge distribution is as follows: ρo for 0 a. Calculate the total electrostatic energy.
