Calculator based on the formulas of gravitational force (law of universal gravitation) and electric force (Coulomb's law), which calculates any of the variables involved in these forces (masses, charges, distance and resultant force).
As we can see when comparing the formulas, in both cases the force between two masses or charges is directly proportional to the product of their masses or charges and inversely proportional to the square of the distance that separates them.
To learn more about these forces I recommend that you visit these websites:
