Contemporary thinking  holds that the calculation to determine electrostatic force between a point and a sphere is approximated as the force between a point and a point; the sphere is approximated as a point. A simple numerical approximation of a point to sphere interaction using Coulomb’s Law in a spreadsheet shows that the conventional approximation of a point to sphere interaction as a point to point interaction is incorrect. The force between a point and a sphere does not equal the force between a similarly charged point and another point at equivalent distance.
This paper evolves an equation that correctly determines electrostatic force between a point and a sphere and investigates applications of the corrected equation. Given that molecules are effectively charged points interacting with charged spheres, a substantial new electrostatic force at the molecular level is a disruptive concept with profound implications.
The incorrect point to point approximation yields zero net electrostatic force between two Hydrogen atoms at any distance. This paper proceeds to calculate and sum the four forces (F1 to F4) in Figure 2 using the corrected equation to determine the net force at various distances (d) between two Hydrogen atoms.

A radius of 25 pm produces a separation distance of 81pm.
 See Section 8. Using 70 decimal places of precision the corrected equation presents a force of 4.8e-49N at 1m. The expected result is 1.8e-64N.
