Find the minimum electrostatic force that can exist between two charges separated by distance 1m.

Explanation

The smallest charge is `±e`. So, the minimum force will be when both the bodies have charge `±e`.
`therefore` Magnitude of minimum force,
`F_("min") = (ke.e)/( 1^2) = ke^(2) = 2.3 xx 10^(-28)` N
