Do electric charges attract or repel?
The electric field and resulting forces produced by two electrical charges of the same polarity. The two charges repel each other. If a positive charge and a negative charge interact, their forces act in the same direction, from the positive to the negative charge.
Is it possible that two like charges attract each other?
yes they can attract each other when one of them is very very large than the other then the electrostatic force acting on the two is not due to their initial charges but will be due to the charges produced due to induction. and hence attraction takes place.
Why charges attract or repel each other?
When a positive charge is brought closer to a negative charge, excess number photons from the positive charge get transferred to the negative charge, so that the number of photons in both the charges are balanced. Therefore, like charges repel and unlike charges attract.
Do like charges attract?
Coulomb’s law,(1) first published in 1784 by French physicist Charles de Coulomb, is one of the most fundamental laws of science that describes the electrostatic interaction between electrically charged particles. According to this classical law, particles with like charges repel and those with unlike charges attract.
What happens to negative charges over time?
the negative charges move to the conductor and exit the object. the object.
What type of charges attract each other?
According to Coulomb, the electric force for charges at rest has the following properties: Like charges repel each other; unlike charges attract. Thus, two negative charges repel one another, while a positive charge attracts a negative charge. The attraction or repulsion acts along the line between the two charges.
Can two like charges attract each other can a charged body attracts uncharged body?
Yes, a charged body attracts an uncharged body as the oppositely charged bodies attract each other. This is known as the force of attraction.
How do like charges repel each other?
Like charges repel each other; unlike charges attract. Thus, two negative charges repel one another, while a positive charge attracts a negative charge. The attraction or repulsion acts along the line between the two charges. The size of the force varies inversely as the square of the distance between the two charges.
What is the minimum charge on a particle?
The minimum charge that a particle can have is the 1.6×10−19 coulomb. A given particle cannot have a charge lower than this.
What type of charge is rubbing two objects together?
How Triboelectric Charging Works. The triboelectic charging process (a.k.a., charging by friction) results in a transfer of electrons between the two objects that are rubbed together.
What happens when two negatively charged balloons are placed next to each other?
Negative charges attract to positive charges. If a balloon is not rubbed with the wool cloth, it has an equal amount of negative to positive charges, so it will attract to a rubbed balloon. When both balloons are rubbed with the wool cloth, the both receive negative charges, so they will repel each other.
Why do opposite charges repel / attract each other?
You must perceive then that the “why opposite charges attract” with the answer “because that is what we have observed” becomes “because we have modeled mathematically the observations successfully”. Then the question becomes why this mathematical model, and the answer is “because it describes the observations”, circular.
When do two particles with the same charge repel each other?
When talking about charged particles, the law of charge dictates that two particles with opposite charge will attract each other and two particles with the same charge will repel each other.
Are there electric charges that attract each other?
No I just forgot to give my answers. Sorry my answers are 9)? 10)? 12 is a 13 is b 8 is b 5 is c 4 is b 2 is b connections student is correct. I promise these are correct. I took the test. Hope this helps! Olivia is correct. Just took the practice, these are the answers. In this order 1 – 14. 1. A 2. B 3. A 4. B 5. C 6. C 7. A 8. B 9. C 10. A 11.
Why do positive and negative electric charges exist?
Physics can be successfully modeled mathematically with postulates and using the model one can show how the behavior of positive and negative charges under all sorts of experimental conditions can be predicted accurately, but not “why” they exist. The why gets the answer “because that is what we have observed nature to do”.
