## How does the electrical force relate to the distance between two charged objects A It is inversely proportional to the square of the distance B it is directly proportional to the square of the distance C it is inversely proportional to the distance d it is directly proportional to the distance?

The size of the force varies inversely as the square of the distance between the two charges. Therefore, if the distance between the two charges is doubled, the attraction or repulsion becomes weaker, decreasing to one-fourth of the original value.

## How does the electrical force relate?

How does the electrical force relate to the charge of an object? It is directly proportional to the charge. … They are inversely proportional to the square of the distance. One charge is decreased to one-third of its original value, and a second charge is decreased to one-half of its original value.

## Do electrical forces act at a distance?

Like gravity, electric force “acts at a distance”. … Unlike gravity, there are two types of electric charge, (whereas there is only one type of gravity; gravity only attracts). Unlike charges attract, Like charges repel.

## Why is attractive force negative?

That’s all right,but I want to know whenever we use a work done by an attraction force we use a negative sign,viz: the gravitational potential.It is written in books that the gravitational potential is negative because the work to bring an object from infinity to the gravitational field is done by the gravitational

## Why force is inversely proportional to square of distance?

This is because the force acts uniformly in all directions from the point source and conserves the energy over the entire surface surrounding the point object. Therefore, the force reduces as the square of the distance. …

## What is an example of a distance force?

Forces can be divided into those that act by direct contact—such as when you push on a door to open it—and those that act at a distance, where there is no apparent physical contact between the objects. Magnetism, and electrical charge, and gravitation are examples of forces that act at a distance.

## Is gravity a non-contact force?

The most familiar non-contact force is gravity, which confers weight. In contrast a contact force is a force which acts on an object coming physically in contact with it. All four known fundamental interactions are non-contact forces: Gravity, the force of attraction that exists among all bodies that have mass.
