# How do you tell if charges repel or attract?

Contents

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.

## How can you tell the difference between a positively charged object and a negatively charged object by using an Electroscope?

If you bring a positive object near the electroscope, it will attract the electrons toward the terminal. The leaves will move away from each other. … In this case, grounding the electroscope with your finger will allow extra electrons to move to the electroscope, which will become negatively charged.

## What is an example of like charges repelling?

Like Charges Repel and Unlike Charges Attract Each Other: Experimental Verification. A charged glass rod is suspended by a silk thread, such that it swings horizontally. Now another charged glass rod is brought near the end of the suspended glass rod. It is found that the ends of the two rods repel each other (Fig 1).

## Can we say that a charged object attracts an uncharged object by first charging it through induction explain your answer?

Yes we can. Actually a charged object always attracts an object which is opposite in charge. … So a charged object tries to attract an object by imparting negative charges to one side of the uncharged object and that process of imparting negative charge is called induction.

## What happens when something is positively charged?

If an object has a positive charge, that means it has lost some electrons and now has more protons than electrons.

## Why do charges repel or attract?

Originally Answered: Why same charge repel and opposite charge attract? Whenever two like charges are placed near each other, they start exchanging a virtual photon amongst themselves, which transfers the momentum between them, and thus they appear to repel each other.

## How do charges attract and repel?

If a positive charge and a negative charge interact, their forces act in the same direction, from the positive to the negative charge. As a result opposite charges attract each other: The electric field and resulting forces produced by two electrical charges of opposite polarity. The two charges attract each other.

## How can a charged object attract an uncharged object made of non conducting material?

How can a charged object attract an uncharged object made of non-conducting material? … The uncharged object must somehow gain an unlike charge. The charges in the uncharged object can become polarized. Attraction of an insulator is not possible.

## When a charged object touches an uncharged object what happens?

Charging an object by touching it with another charged object is called charging by conduction. By bringing a charged object into contact with an uncharged object, some electrons will migrate to even out the charge on both objects. Charging by conduction gives the previously uncharged object a permanent charge.

## Why does a charged object lose its charge when touched?

When we touch such an object, the extra charges tries to flow through our body to the ground or the earth. This happens because the earth is deficient in charges as compared to the charged object. As a result of this difference, the extra charges in the object flows into the earth through our body.

## What types of charges attract?

Opposites attract.

These two types of electrical charges – positive and negative – are said to be opposite types of charge. And consistent with our fundamental principle of charge interaction, a positively charged object will attract a negatively charged object.

## Does static electricity repel or attract?

Static electricity is the buildup of electrical charge in an object. … This happens when objects have opposite charges, positive and negative, which attract. (Objects with the same charges repel one another.)

## 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.
