Coulomb's law states that the electrostatic force between two point charges is directly proportional to the product of the charges and inversely proportional to the square of the distance between them. The expression for Coulomb's law is F = k * (|q1 * q2|) / r^2, where F is the force, k is the electrostatic constant, q1 and q2 are the magnitudes of the charges, and r is the distance between the charges.
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
The mathematical expression is Q = nF, where Q is the total charge in coulombs, n is the number of moles of electrons transferred (in this case, 3 moles for iron III sulfate to iron metal), and F is the Faraday constant (96,485 C/mol). Therefore, the number of coulombs necessary would be Q = 3 * 96485 C/mol = 289,455 C.
How do you write an expression
yes
The unit of the constant of proportionality in Coulomb's law is Nm²/C² or Vm.
78 + yz = yz + 78
the same : expression
newtons * meters squared / coulombs squared
You can always write a numerical division expression as a decimal.
