Question: What charges attract and what charges repel?

Contents

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.

What do charges attract?

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.

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).

Why 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.

Do like charges attract or repel?

Like charges repel each other; unlike charges attract. Thus, two negative charges repel one another, while a positive charge attracts a negative charge.

Why like charge repel each other and unlike charge attract 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. Hence, the correct answer is option A.

Under what conditions do charges attract and repel each other?

Under what conditions do charges attract or repel each other? Two like charges (positive or negative) repel each other and two unlike charges (one positive and one negative) always attract each other.

Do electrostatic charges attract or repel each other explain?

Attraction and repulsion of electric charges is one of three fundamental non-contact forces in nature. … Positive and negative charged objects attract or pull each other together, while similar charged objects (2 positives or 2 negatives) repel or push each other apart.

Why do two objects with the same charge repel?

They repel or attract each other because of their electric field. Positive and Negative charge have electric field in opposite direction. For Ex. Negative charges have electric field towards them.

What is the law of electric charge?

Electric charge is a basic property of electrons, protons and other subatomic particles. Electrons are negatively charged while protons are positively charged. … Things that have the same charge push each other away (they repel each other). This is called the Law of Charges.

What makes a charged object attract an uncharged object?

When we put a charged object near an uncharged object, it produces opposite charges in the near end of the uncharged object by electric induction. … If we bring it near an uncharged sphere, the sphere forms negative charge near the glass rod, and positive charged on the end away from glass rod.

Can two like charges attract?

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.
