A solid isolated sphere with radius R has a non uniform charge wich is given by ρ= Ar²,
with A a constant and r<R measured from the centre of the sphere
(a) Show that the electric field outside the sphere is equal to E = (AR5)/(5ε0r²)
(b) Show that the electric field inside the sphere is equal to E = (AR3)/5ε0)
