# Which of the following changes would create an increase in electric force?

Contents

A doubling of the quantity of charge on one of the objects results in a doubling of the electric force. A tripling of the quantity of charge on both of the objects results in an increase in the electric force by a factor of 6.

## What increases electric force?

In electrostatics, the electrical force between two charged objects is inversely related to the distance of separation between the two objects. … And decreasing the separation distance between objects increases the force of attraction or repulsion between the objects.

## What happens to the electric force as charge increases?

According to Coulomb, the electric force for charges at rest has the following properties: Like charges repel each other; unlike charges attract. … If the charges come 10 times closer, the size of the force increases by a factor of 100. The size of the force is proportional to the value of each charge.

## What is electric force?

Electric Force: force exerted by two charged objects. Positive/Negative Charges: two unlike charges will exert a force that attracts each other while two like charges will exert repelling forces on each other.

## What two factors have an affect on the force between the two charges seen in the simulation?

Charles Coulomb determined how to figure out the strength of the force between charged particles. As we’ll discuss in this lesson, he found that the force between charged particles was dependent on only two factors: the distance between the particles and the amount of electric charge that they carried.

## Is electric force attractive or repulsive?

Second, gravitational forces are only attractive; electrical forces can be either attractive or repulsive. The inverse square relationship between force and distance that is woven into the equation is common to both non-contact forces.

## Can electric field be negative?

Electric field is not negative. It is a vector and thus has negative and positive directions. An electron being negatively charged experiences a force against the direction of the field. For a positive charge, the force is along the field.

## What happens to the force when the distance is doubled?

Hence force of attraction will be quadrupled. (1) When distance between objects is doubled, force of attraction will become 122=14 times i.e. will become one-fourth. (3) When distance between objects is halved, force of attraction will become 1(12)2=114=4 times i.e. will become four times.

## What is the minimum charge on a particle?

The minimum charge that a particle can have is the 1.6×1019 coulomb. A given particle cannot have a charge lower than this.

## At which position would the electric force be greatest?

Electric field strength is greatest where the lines are closest together and weakest where lines are furthest apart.

## Why is electric force important?

In general, electrostatic forces become important when particle material is electrically insulating so the electric charge can be retained. … In electrophotography, electrostatic forces are utilized to move charged toner particles from one surface to another for the purpose of producing high-quality prints.

## Why r2 is used in Coulomb law?

The squaring at denominator has to do with the area involved. (Of a sphere to be precise.). Because when charges repel to each other .. then distance between them also increase with the factor of r square….. I assume the question is about “point” rather than about charge in general.

## What are the similarities and differences between electric force and gravitational force?

Electric vs Gravitational Force

Similarities Differences
Both have fields Electric force can be both repulsive and attractive but gravity only attracts
Both have potential lines Electric force results from charge but gravitational force results from mass

## What is the direction of the force on the test charge due to the two other charges?

The direction of the force vector depends on the sign of the charges. If the charges are the same, the force points away from the other charge. If the charges have different signs, the force points toward the other charge((Figure)).
