Coulomb's law is applied to point charges because there are "problems" applying it to a charge that has "dimension" to it. A charge is surrounded by an electric field. If we cannot treat it as a point, then the charge has to be "distributed" through the "body" of the charge. It will change the way we have to do the math. If we view charges as non-point sources, then we can't apply the mathematics to the charges in quite the same way as we do when we work things out with point sources. Take a charge that isn't a point source and one that is. If the charge that isn't a point source has "dimension" to it, then the charge on that charge (if that makes sense) is not eminating from a point but from the "body" of the charge as a whole. The electric field will be "distributed" over the volume of the body of the charge, and its effect on a point source will have to be worked out differently than it would if it was point source-to-point source.
What else can I help you with?
What electric charges are not observed in matter on the atomic scale?
Only integer multiples of the elementary charge (1.6 x 10^-19 coulombs) are observed in matter on the atomic scale. Non-integer or half-integer values of charge are not observed in nature.
What is a point charge?
A point charge is a theoretical concept used in physics to represent a concentrated charge at a single point in space. It simplifies calculations involving electric fields and forces by treating the charge distribution as being located only at a single point.
What are the limitations of coulomb's law?
coulombs law is valid if the average number of solvent molecules between two interacting charges is large enough that the properties of the micro region of solvent can be expected to b similar to that of the bulk solvent.
What does is mean to say a charge is quantized?
It means the charge is an integer multiple of some basic charge. If the charge consists of a certain number electrons, you can have 1 electron, 2 electrons, 3 electrons, etc., but you can't have 1.5 electrons, or pi electrons.
Why can't coulomb's law be applied to charged object that are very close to each other?
Actually Coulombs law is applicable only for point charges but not for bodies. But while calculating the electrostatic force between two spherical charged bodies they supposed as point masses(objects) but the distance seperation should be more greater than their radii. Otherwise the charge on one body can influence charge on another body.
How is coulombs law different from newton law?
Newtons law has to due with mass and ATTRACTION only Coulombs law has to due with charge and ATTRACTION AND REPULSION
How do you calculate how much energy a battery has with only the volts and coulombs?
To calculate the energy stored in a battery with volts and coulombs, you can use the formula: Energy (Joules) = Voltage (Volts) x Charge (Coulombs). Multiply the voltage by the charge of the battery to get the energy capacity in Joules.
A 1000 uF capacitor hold 9.2 coulombs of charge what is the voltage on the capacitor?
9200 volts my 1000 uF capacitor only holds 10 volts

The charge of electrons?
Electrons have a negative charge. The easy way to remember it is because the names of the other two particle types which make up an atom sound like what they are: Proton is Positive Neutron is Neutral So you're only left with the negative charge, which must be assigned to the electron.
How many faradays of charge does a single electron have?
There is less than one faradays of charge in a single electron. It takes thousands of electron to charge anything and only either protons or neutrons are capable of charging a single electron.
What is a point charge?
A point charge is a theoretical concept used in physics to represent a concentrated charge at a single point in space. It simplifies calculations involving electric fields and forces by treating the charge distribution as being located only at a single point.
How would you calculate the amperage for a strobe circuit with only the known values of farads volts joules and coulombs?
Amps are coulombs per second, and there is no information on rates given here.
What are the limitations of coulomb's law?
coulombs law is valid if the average number of solvent molecules between two interacting charges is large enough that the properties of the micro region of solvent can be expected to b similar to that of the bulk solvent.
What are charge offs?
Charge offs are accounts that have been written off by the creditor as uncollectable. The debt owed is still valid and can be collected on either by the original creditor or by a collection agency. You can only erase charge offs by disputing them to the credit bureaus or negotiating the removal by the original creditor.
