The force between two charges (masses) is proportional to the product of the charges (masses) and inversely proportional (same) to the distance between them.
The formula for the force between two charges (masses) has the same exact form in both cases.
Newtons law has to due with mass and ATTRACTION only Coulombs law has to due with charge and ATTRACTION AND REPULSION
newtons * meters squared / coulombs squared
Limitations of coulombs law
No
Both have the concept of variation of force inversely with the square of the distance. But in case of coulomb we have electric charges and in case of newton's gravitation law we have masses. Coulomb's force can be either attractive and repulsive where as Newton's is only attractive

coulombs law
yea
Its a matter of being scientifically rigorous. You can not claim the 2nd law as a law unless you first establish the first law.
It states newtons law of gravitation
newtons first law: she will not move unless an outside force acts upon her, like her feet moving or her partner moving her!
That's the unit for the electric field. The SI units for electric field are, precisely, newtons/coulomb - or the equivalent, volts/meter. This unit doesn't have a special name.
