A radial electric field distribution in free space is given in spherical coordinates as:

= o 3 o ( ≤ ) = (2 3 − 3 )o 3o 2 ( ≤ ≤ ) = (2 3 − 3 )o 3o 2 ( ≥ )

Where, rhoo, a, and b are constants. (a) Determine the volume charge density in the entire region (0 ≤ r ≤[infinity]) by the appropriate use of ∇ .D = . (b) In terms of given parameters, find the total charge, Q, within a sphere of radius r where r > b.
