Charge density causing an Electric Field

    So the problem is: The electrostatic field is E =g|r|r where g is a constant. Find the charge density p(r) which can generate the field?

    My attempt was gauss law: divE=p0

    But I'm struggling to take divE. I guess r=x+y+z?

    Any advice much appreciated!!
