It is experimentally observed that if an insulator is used as medium in place of air or vacuum, the force between the electric charges is reduced by a factor "Er".
The unit of the constant of proportionality in Coulomb's law is Nm²/C² or Vm.
The "Q" in Coulomb's Law represents the magnitude of the point charges involved in the interaction. It is the charge of one of the point charges that determines the strength of the electrostatic force between them.
The variable for charge in coulombs is typically represented by the letter "Q".
A statement that is not true for Coulomb's law is that the force between two charges depends on the type of material the charges are made of. Coulomb's law only depends on the magnitude of the charges and the distance between them, not on the material properties.
There are approximately 1.875 x 10^19 electrons in 3 coulombs of charge. This is based on the charge of an electron being 1.6 x 10^-19 coulombs.
Limitations of coulombs law
No
Newtons law has to due with mass and ATTRACTION only Coulombs law has to due with charge and ATTRACTION AND REPULSION
coulombs law
yes
The unit of the constant of proportionality in Coulomb's law is Nm²/C² or Vm.
medium
newtons * meters squared / coulombs squared
nick who?
it is mediam
