Hi I have this problem that I cannot find the solution:
2 students propose the following 2 different flux densities as solutions to an electrostatics problem:
D1= ε* ρ^2 ρ (ρ, φ unit vector)
D2= ε*ρ^2 *(sin(φ))^2 ρ+ 3*ε*ρ*z*(cos(φ))^2φ
Show that the volume charge densities that correspond to these two fields are identical.
I tried to apply the divergence to D1 and D2 but I don't find the same response.
So I dont know what else I can do here.
Please can I have some help?
