Two equal charges exert equal forces on each other What if one charge has twice the magnitude of the other?
Whatever be the magnitude of charge, two charges will always exert equal force on each other. As force depends on the product of magnitude of charges, it will increase if magnitude is doubled but will remain same for both the charges.
Why like charges repel and unlike charges attract each other?
The reason why some charges repel while unlike charges attract comes down to polarity. According to Newton, with every action there is an equal and opposite reaction. The reason comes down the the amount of protons and electrons in each atom. Equal amounts produce a repelling action where as charges with unequal protons and elections will cause the atoms to attract.
When there is an equal amount of positive and negative charges on an object what is the object?
As equal amount of positive and negative charges are there then the net charge on the object is the algebraical sum of them and hence it becomes zero. So chargeless.
What kind of charges will a sheet of paper have after it has been rubbed with wool or fur with silk?
In a atom there are negative,positive as well as neutral charges. The positive charges(proton) and the neytral charges( neutron) are held together in nucleus by strong electrostatic forces. The negative charges( electron) keeps on revolving around the nucleus. A neutral atom has a equal number of positive and negative charges which balances each other. Now when the sheet of paper have been rubbed with wool then the negative charges gets attracted to the wool and due to the lack of negative charges the paper becomes positively charge.And so is the fur when rubbed with silk.
How do you calculate the electric force between two charges?
electric force between 2 charges is equal to product of the amount of charge(in units) of both particles and a constant 9*109 divided by the square of the distance between them.
One Faraday is equal to coulombs?
1 faraday = 9.6485 x 104 coulombs (rounded)
What is an abcoulomb?
An abcoulomb is a unit of electromagnetic charge equal to ten coulombs.
What does an electron have?
The electron has a negative charge equal to -1.602 176 565(35) × 10-19 coulombs.
Charge on an electron is equal to?
The charge of an electron is -1,602 176 620 8(98)×10e-19 coulombs.
Can the charge on an electron be changed?
No. The charge on the electron is fixed at -1 (which is also equal to 1.602177 x 10-19 Coulombs).
What does a protons Carry?
A single positive charge, (elementary charge, e, value, 1.602176565(35)×10−19 coulombs).the electron has an equal and opposite charge.
What is the unit of potential difference between two points?
The unit of potential difference in a circuit is the volt.Electrical charge is measured in coulombs (1 coulomb = 6.241x1018 e, electron charges) and a volt is equal to 1 newton per coulomb at a distance of 1 meter.
Does a polar molecule have both unequal and equal charges?
It has two opposite charges
Calculate the theoretical number of moles of copper that should have plated out onto the brass key?
First you have to find the coulombs. Then you convert coulombs to faradays. (there are 96500 coulombs in one faraday). 1 faraday is equal to one mole electron. Then, by using a half-reaction of the anode (Cu + 2e- > CuS), you can determine there are 2 mole electrons for every mole of copper.
What is a good comparison of the charges of an electron and the charges of a proton?
They are equal in magnitude but opposite in charge.
Why did Buddha reject the caste system?
It was against his teachings. He believed everybody was equal.
What is total positive charges and negative are equal?
You mean, what happens when positive and negative charges are equal? That is simple, the equal opposite cancel each other out and we have an electrical neutrality
