In a previously derived geometry-based energetic expression, the Newtonian gravitational constant (G) is apparently related to the Planck constant (h) such that the accepted value of G can be calculated from that of h. Here, based on that expression, the relation between Newton’s law of universal gravitation and Coulomb’s law is evaluated. This evaluation in turn yields the apparent relation between G and the Coulomb constant (k_e) that G/k_e = [m/(c s)]^2[10^(-3)*(1+1/phi^2)ln(phi^2) - h*10^30 s/(kg m^2)](C/kg)^2 and, furthermore, the relation that c = {alpha/[2pi*G(q_e)^2]}[ h*10^(-3)*(1+1/phi^2)ln(phi^2) – h^2*10^30 s/(kg m^2)](s C / m kg)^2, in which c is the speed of light in vacuum, q_e is the elementary charge with the unit C, alpha ...
