[FEAT] Add Coulomb's Law for electrostatics

[Priyanshu1303d]

Hello! This PR adds a new physics algorithm, Coulomb's Law (CoulombsLaw.java), to the physics module.
This utility class is the electrostatic equivalent of the Gravitation algorithm.

Hello @alxkm, @DenizAltunkapan, @yanglbme,

I was running the full mvn test suite to verify my changes, I discovered a pre-existing bug in JugglerSequence.java that was causing the build to fail.

this commit includes both my new CoulombsLaw feature and the fix for JugglerSequence.java. All tests now pass locally with a BUILD SUCCESS. ✅

Thanks for your time!
