Can 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..
What happens when Amber and cotton are rubbed together?
When glass is rubbed with silk the glass becomes positively charged. When amber is rubbed with fur the amber becomes negatively charged. All these things were neutral to start with, in other words they had equal numbers of positive and negative charges.
Is plastic positively or negatively charged?
Choice of the names negative or positive is arbitrary. If you rub a glass rod with a cloth, the charge produced on the glass rod is called positive, whereas when a plastic rod is rubbed with a cloth, the charge produced on the plastic rod is negative.
Why is attractive force negative?
You would have learnt this thing in chemistry (In Atom Structure, you would have calculated energy of electrons for different energy levels b/w electron & proton(nucleus)), that attractive force reduces the energy of the electrons and repulsive force increases the energy of electrons) So since energy corresponding to …
Why does OH have a negative charge?
The formula for hydroxide is OH-. In this compound, oxygen bonds with hydrogen by sharing two electrons. Hydroxide carries a negative charge because it has gained an electron.
Is Amber positive or negative?
Under normal circumstances, only the electrons are mobile. Thus, when amber is rubbed with fur, electrons are transferred from the fur to the amber, giving the amber an excess of electrons, and, hence, a negative charge, and the fur a deficit of electrons, and, hence, a positive charge.
Why do negative charges attract positive?
A negative charge wants to give away its electrons to become neutral therefore it attracts positive charge towards it. On the other hand, a positive charge requires electrons to become neutral, that is why it moves towards negative charge.
What is a negative charge?
Noun. 1. negative charge – having a surplus of electrons; having a lower electric potential. electric charge, charge – the quantity of unbalanced electricity in a body (either positive or negative) and construed as an excess or deficiency of electrons; “the battery needed a fresh charge”
Who decided electrons are negative?
Benjamin FranklinBenjamin Franklin was the one who first chose to call electrons negative and protons positive. According to the textbook “Physics for Scientists and Engineers” by Raymond A.
Why do neutral and charged objects attract?
Neutral object are attracted to either charge. … The region that has too many electrons is negatively charged, the other region positively, because of lack of electrons. The positive region since it is closer to the charge will be attracted to this charge. This process is called induction.
What are 3 examples of static?
What are three examples of static electricity? (Some examples might include: walking across a carpet and touching a metal door handle and pulling your hat off and having your hair stand on end.) When is there a positive charge? (A positive charge occurs when there is a shortage of electrons.)
What is the amber effect?
The triboelectric effect is a type of contact electrification in which certain materials become electrically charged after coming into contact with another different material, and are then separated.
Why is hair attracted to acetate?
This is because the rubbing creates a negative charge that is carried by electrons. The electrons can build up to produce static electricity. … Consequently, when you pull the balloon slowly away from your head, you can see these two opposite static charges attracting one another and making your hair stand up.
What is a positive or negative charge?
There are two types of electric charge: positive and negative (commonly carried by protons and electrons respectively). … If there are more electrons than protons in a piece of matter, it will have a negative charge, if there are fewer it will have a positive charge, and if there are equal numbers it will be neutral.
What happens when positive and negative charges meet?
Opposite charges attract each other (negative to positive). Like charges repel each other (positive to positive or negative to negative). Most of the time positive and negative charges are balanced in an object, which makes that object neutral. … The electrons cling to your body until they can be released.
Is Cotton positively or negatively charged?
When rubbed together, the plastic spoon will attract and steal electrons from the cotton. This means the spoon has a greater number of electrons than protons making it have a negative charge. Since the cotton lost some electrons, it is now positively charged (since it now has more protons than electrons).
