	Talk:Coulomb's law - Wikipedia, the free encyclopedia
		So perhaps we could reformulate Coulomb's Law as a statement along the lines of "as the limit of the particles' volumes goes to 0..." But if this is so, how are we to think about the lowest levels of matter, where everything seems to be quantized, not continuous?
		Coulombs law is usually stated as giving the force on a small test charge.
		In typical applications Coulombs law is a very useful approximation.

	Electric forces
		Coulomb's law is a vector equation and includes the fact that the force acts along the line joining the charges.
		Coulomb's law describes a force of infinite range which obeys the inverse square law, and is of the same form as the gravity force.
		The constant of proportionality k appearing in Coulomb's law is often called Coulomb's constant.

		The laws of physics which, for example, describe the behavior of diffraction gratings (see Harrison) were true from time immemorial and it is because of those laws that diffraction gratings, when they came to be engineered in modern times, have the peculiar properties they do.

	Talk:Electromagnetic induction - Wikipedia, the free encyclopedia
		As a capacitor is the dual of an inductor,there must be an equivalent law to 'Lenzs law' that applies to a capacitor in an electric field with changing electric flux (density).
		Now this law is equivalent to saying that you can't change the voltage on a cap instantly (we all knew that).
		Hi, Coulomb's Law is known by everybody, and still i have a question no one around me can answer.

	Charge and Coulomb's Law - Wikibooks, collection of open-content textbooks
		Due to their mutual repulsion (calculable via Coulomb's Law [1]), the valence electrons are forced from the center of the object and spread out evenly across its surface in order to be as far apart as possible.
		The SI definition of a coulomb is the quantity of charge which passes a point over a period of 1 second (s) when a current of 1 ampere (A) flows past that point, i.e., C = A s or A = C/s.
		An ampere is one of the fundamental units in physics from which various other units are defined, such as the coulomb.

		Coulomb's Law- Law which supposedly governs the forces of attraction or repulsion between electrical charges.
		However, Coulomb's Law, it is now known, can only refer to interactions between charged particles which have a common de Broglie wavelength which is less than the interparticle distance.
		But Newton's third law of motion, as articulated above, could be erroneously argued to contain the implied idea that two particles which have relative motion don't really have equal and opposite momenta until they interact in some local and physical fashion (such as an elastic collision).

	Modern Physics:Coulomb's Law and the Electric Field - Wikibooks, collection of open-content textbooks
		The repulsive or attractive electrostatic force between two point charges is determined by an equation called Coulomb's law.
		The value of Coulomb's constant given here is such that the preceding Coulomb's Law equation will work if both q and Q are given in units of coulombs, r in meters, and F in newtons and there is no dielectric material between the charges.
		Based on Coulomb's Law, the magnitude of this force vector is typically proportional to the charge of the particle.

	Coulombs Law
		To verify the proportionality of Coulomb's Law that the electric force between two point charges is directly proportional to the product of the charges and is inversely proportional to the square of the distance between them.
		Coulomb's Law gives us the static electrical force F, exerted by a point charge Q
		In this experiment, we will verify this law and also learn how to use an optical lever to magnify a small rotation into a large displacement.
