is there any method to find the force between two charged particles other than Coulombs Law ?

we have the famous "CARL FRIEDRICH GAUSS's LAW ".Indeed we have more fundamental laws but they are too high level...............................

isn't Gaus's Law derived from Coulomb's Law?

gauss law is more fundamental than coloumbs law........... SOURCE:RESNICK,HALLIDAY AND KRANE

Gauss derived his law from coluomb but it is interesting that in large limit the coulomb's law fails but probably not Gauss's Law.

Ok apart from gauss's and Coulomb's Laws there is no method to find force between two charged particles?

I don't know once my physics teacher showed me some pages of " FEYNMAN LECTURE" they contained a law which was the modified Coloumb's law and contain 2-3 terms more apart from the usual coloumb's law.

Yes, it can be done by using a torsional balance ( a sensative device used to measure force ). Even coulomb used the same to measure the force between two charged metallic spheres. If you would remember, cavendish used it to measure the feeble gravitational force between two objects to verify newton's law of gravitation.

there are a large number of ways like guass law, mirror image principle, symmetry concepts, and co-ordinate calculations using mathematical principles.....but coulomb's law is preffered bcos it is geeric ie. applies to all cases ......others are special cases and are derivable from coulomb law itself.. rate if helpful nudge if problem persists
|
all the best ... |

first or all coulomb law is not method it is just a formula based on observation and experiment done by coulomb, and second thing is that for a student you can call this as method to write force between charges but this formula just gives electrostatic component, there may be magnetic component also.
