It is analogous to Newtons' law of gravitation in that it relates the force on each particle to the inverse square of the distance between them.
This law is only truly accurate in a stationary system because, under motion, magnetic fields alter the interactions between particles. This law uses the constant k which is approximately equal to 9 billion newtons (*) times meters squared over its namesake's SI unit squared. It is analogous to Newtons' law of gravitation in that it relates the force on each particle to the inverse square of the distance between them. FTP, name this law for electrostatic force dependant on charge named after a French physicist.
This law is only truly accurate in a stationary system because, under motion, magnetic fields alter the interactions between particles.
