## How do electric charges interact?

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.

What happens to the electric force between two charges when the distance between them was increased?

In electrostatics, the electrical force between two charged objects is inversely related to the distance of separation between the two objects. Increasing the separation distance between objects decreases the force of attraction or repulsion between the objects.

### How does the electric field between two charged particles depend on the distance between them?

Coulomb Basics The law looks at the forces created between two charged objects. As distance increases, the forces and electric fields decrease. The force between the objects can be positive or negative depending on whether the objects are attracted to each other or repelled.

Can electric attraction act at a distance?

The electric force acts over the distance separating the two objects. Electric force is an action-at-a-distance force.

## What happens when like charges interact?

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.

How do the two kinds of charges interact with each other?

The interaction between two like-charged objects is repulsive. Positively charged objects and neutral objects attract each other; and negatively charged objects and neutral objects attract each other.

### When distance between two charges is reduced to one half of the original distance the force between them will remain the same if one of the charges is made?

Explanation: The force between the two charges is directly proportional to the product of the charges and inversely proportional to the square of the distance between them. Hence, if distance between charges is halved (charges remaining kept constant), the force between the two charges is quadrupled.

Does the force on a charge depend on the magnitude of the charge?

The magnitude of the force is linearly proportional to the net charge on each object and inversely proportional to the square of the distance between them. (Interestingly, the force does not depend on the mass of the objects.)

## How does mass and distance affect the force of gravity between two objects?

The force of gravity depends directly upon the masses of the two objects, and inversely on the square of the distance between them. This means that the force of gravity increases with mass, but decreases with increasing distance between objects.

What happens when two electrically charged objects attract each other?

Electrostatic interactions are commonly observed whenever one or more objects are electrically charged. Two oppositely-charged objects will attract each other. A charged and a neutral object will also attract each other. And two like-charged objects will repel one another.
