A solid sphere that is uniformly positively charged produces an electric field. Assume no other objects are around. What is the magnitude of the electric field a distance r from the center of the sphere if the Coulomb constant is $9\mathrm{.}00$E$+09,$ the charge per unit volume of the sphere is $0\mathrm{.}348,$ the volume of the sphere is $0\mathrm{.}667,$ and the distance r from the center of the sphere is $0\mathrm{.}454?$   find the answer in SI units.
