Summing four forces in a point and solid circle approximation of two Hydrogen atoms at close distance. Solid circles are approximated by many shells.

These parameters are used to determine the 4 electrostatic forces in a two Hydrogen system with one Hydrogen moving away from a fixed Hydrogen, calculating net force at various distances. Results are dumped in the textbox below, one row per increment of distance. Paste the output below into Excel for graphing. Note Excel will remove any precision greater than 16 decimals. Large values for number of increments or number of shells can take considerable time.
