Detailed Description

Coulomb electrostatic force.

The force acts between pairs of charged bodies (currently only ChargedParticle) and equals:

where:
is CoulombForce::coulombConst
and is ChargedParticle::charge of the first and second body
is difference of Particle::position of the first and second body

Todo:

Add interface for charged bodies, support bodies with distributed charge
