Q) Is there any lower limit to the electric force between two charges at a separation of 1 cm?
A) Yes,
there is a lower limit of electric force between two charges for a given medium.
Because the charge is QUANTISED IN TERMS OF CHARGE OF ELECTRON.
Thus, all the quantities affiliated with charge has to be quantised.
Therefore teh minimum electric force or lower limit exists when the two charges are electrons or both are protons or 1e and 1p.
In all these conditions the magnitude of electric force is
F = ke2 / (0.01)2 N
Here k = 1/4
0 , when it is vacuum.
