# What is potential difference uniform electric field

• Blitzp22
In summary, potential difference is the difference in electric potential between two points in an electric field, measured in volts (V). An electric field is a region where electrically charged objects experience a force, created by electric charges and represented by lines of force. A uniform electric field has a constant strength and direction, typically produced by two parallel plates with opposite charges. In a uniform electric field, potential difference is directly proportional to distance and affected by the strength of the field. The unit of potential difference in a uniform electric field is volts (V), equivalent to one joule per coulomb.

## Homework Statement

What is the potential difference (in V) between xi = 18.5 cm and xf = 82.2 cm in the uniform electric field Ex = 4920 V/m?

Not sure?

## The Attempt at a Solution

Its simple but I am having problems figuring it out. I have a feeling it has to do with q1 and q2.

Solved. Not as bad as I thought

Potential difference in a uniform electric field refers to the difference in electric potential between two points in the field. It is measured in volts (V) and is dependent on the strength of the electric field and the distance between the two points. In this case, the potential difference between xi = 18.5 cm and xf = 82.2 cm can be calculated using the formula:

ΔV = Ex * Δx

Where ΔV is the potential difference, Ex is the strength of the electric field, and Δx is the distance between the two points.

Plugging in the given values, we get:

ΔV = (4920 V/m) * (82.2 cm - 18.5 cm)

= 315,180 V

Therefore, the potential difference between the two points is 315,180 V.

## 1. What is potential difference?

Potential difference, also known as voltage, is the difference in electric potential between two points in an electric field. It is measured in volts (V) and represents the amount of energy required to move an electric charge from one point to another.

## 2. What is an electric field?

An electric field is a region in space where electrically charged objects experience a force. It is created by electric charges and is represented by lines of force that show the direction and strength of the force.

## 3. What is a uniform electric field?

A uniform electric field is a field with a constant strength and direction. This means that the field lines are evenly spaced and parallel to each other. It is typically produced by two parallel plates with opposite charges.

## 4. How is potential difference related to uniform electric field?

In a uniform electric field, the potential difference between two points is directly proportional to the distance between them. This means that the greater the distance, the greater the potential difference. It is also affected by the strength of the electric field, with a stronger field resulting in a larger potential difference.

## 5. What is the unit of potential difference in a uniform electric field?

The unit of potential difference in a uniform electric field is volts (V). One volt is equivalent to one joule per coulomb, which represents the amount of energy required to move one unit of electric charge (coulomb) between two points in an electric field.
