Charge is distributed within a sphere of radius R with a volume charge density p(r)=A/r2e^−2r/a, where A and a are constants. If Q is the total charge of this charge distribution, the radius R is : Charge is distributed within a sphere of radius R with a volume charge density p(r)=A/r2e^−2r/a the radius R is : where A and a are constants.
