Formula of coulomb's law?

Limitations of coulombs law

coulombs is the ___________________________

Newtons law has to due with mass and ATTRACTION only Coulombs law has to due with charge and ATTRACTION AND REPULSION

Q refers to charges. Charges are measured in coulombs.

Coulombs law is similar to Newtons law of Gravitation in that each force has an inverse square relation with the distance between the two bodies interacting. Coulombs law can be applied to the repulsive force of like charges as well, where as gravity is only an attractive force.

Both show force is inversely proportional to the square of distance and directly proportional to the product of 2 masses, for gravity or 2 charges. for Coulombs law.

An ampere is coulombs per second. It is also voltage times resistance. (Ohm's law) Answer There is no 'formula' for an ampere. An ampere is defined in terms of the force between two, parallel, current-carrying conductors. This is a definition, not a formula.

It is quite similar to the general law of gravitation.

Both involve an inverse square law.

Coulumbs law is applicable only for static fields that is when charges are stationary

The force between two charged particles.

(4 coulombs / 2 seconds) = 2 coulombs per second = 2 Amperes.

The similarities come in the way of the "form of the equation". Newton's law: F=g*[m1m2/r2] Coulombs law: F=k*[q1q2/r2] they are both inverse square laws and both multiply one property of each material together and have a constant factor [g in newton's and k in coulombs]

One difference is that electrical attraction can be both attractive and repulsive.

Both are 'Inverse square' forces, f=k/r2 .

They have the same dependence on distance between two charges/particles.

Yes. The forces are mutual.

You may use the solid angle concept to prove it mathematically.

The law is: Needed electricity in coulombs = Faraday constant (96500 C) x number of moles So 96500 coulombs are needed.

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 * meters squared / coulombs squared

The area of Germigny-sous-Coulombs is 6,530,000.0 square meters.

The main use of a Faraday is in the formula Q=nF. If this is rearranged, F=Q/n A Faraday is 96485 coulombs.

Charles Coulomb, though two contributing scientists were Joseph Priestley and Henry Cavendish.

"2 amperes" means "2 coulombs per second" (2 coulombs per second) x (2 seconds) = 4 coulombs
