Thank you.

[@jadakamau7341]

wow this explanation made the concept super easy to understand...thanks a lot

[@PhysicsclassroomVideos]

You're welcome. Glad you got it!

[@Staticspy.001]

Thanks for such a great explanation You've helped me out alot! But I have a question, Will two objects charged differently attract or repel?

thank you mr h 💕

Charging means transfer of charges. How it occur that such a small electron leaves one object and goes to the other? If it is need to be the transformation of possite charges , how is this possible to transfer positive nucleus or proton from an atom leaving electron behind .

[@caitlint6174]

I think you are asking how an atom gets positively charged, I’m not entirely sure. To answer your question, an atom to become positively charged there must be more protons than electrons. Protons are tightly bound to the nucleus and can’t be removed unless there is a nuclear reaction. Although electrons are weakly bound and with the addition of energy it leaves the atom and transfer to a different electron shell. When an electron leaves the atom there would be an imbalance of charges because a neutral charged object has the same amount of protons and electrons (their charges cancel each other out). Therefore the atom would become a positively charged ion. If I am wrong I am sorry, I’m still trying to understand the concept.

@@caitlint6174 my first question is , Two objects which are to be rubbed have huge distance between them still while rubbing , how electrons are covering huge distance between them . Your answer is correct .

Dear Mr H, Why is the neutral charge being attracted to +ve or -ve charge?

[@PhysicsclassroomVideos]

That question is addressed rather thoroughly here: kzbin.info/www/bejne/Y6XZnoigmZ6neMU

Respect sir: why we used inverse squre distance between their center of the charge, sir why we dont used invrse cube law is used?

[@PhysicsclassroomVideos]

The charges electric field spreads outward in all directions across a spherical surface area that is related to distance squared ( as in 4*pi*R^2).
