Question

A voltage difference is applied a long a wire on the x axis, as shown. A positive charge q1 = +2.0 μC moves from left-to-right and a negative charge  q2 = –2.0 μC moves from right-to-left across the dashed line, in a time interval t = 1.0 s. The total electric current moving across the dashed line is:

A.

0 μC/s

B.

4 μC/s, –x direction

C.

2 μC/s, +x direction

D.

4 μC/s, +x direction

E.

2 μC/s, –x direction

**Description of the Electric Field Between Two Charges**

In this diagram, we have two point charges situated on a straight line with a delineation in the middle, indicating their positions and respective voltages.

### Key Elements in the Diagram:

1. **Left Charge**:
   - **Charge**: +2 µC (micro-Coulombs)
   - **Voltage (V)**: +0.2 V (Volts)

2. **Right Charge**:
   - **Charge**: -2 µC (micro-Coulombs)
   - **Voltage (V)**: +0.1 V (Volts)

3. **Arrows Indicating Forces**:
   - There are two arrows. One arrow points from the negative charge towards the positive charge, and another points from the positive charge moving opposite toward the direction of the negative charge, indicating the attractive force between the charges.

### Explanation of the Diagram:

This figure illustrates a situation in electrostatics, where we have a positive charge of +2 µC positioned at a point with a voltage of +0.2 V. To its right, there's a negative charge of -2 µC at a point with a voltage of +0.1 V. The charges experience attraction due to their opposite signs, as indicated by the arrows pointing towards each other.

The dashed line in the middle represents a hypothetical boundary or reference point between the two charges.

### Educational Notes:

- **Electrostatic Force**: The force between two charges, described by Coulomb's Law, is directly proportional to the product of the charges and inversely proportional to the square of the distance between them.
- **Voltage Relationship**: Voltage in this context is associated with the electric potential at a point in space due to these charges. The different voltages illustrate how the potential varies between the two points.
- **Charges Interaction**: Positive and negative charges attract each other. This fundamental interaction is crucial in understanding electric fields and forces in electrostatics.

### Application:

This basic setup is foundational in fields relating to electric circuits, electromagnetic theory, and various applied sciences and engineering disciplines. Understanding these interactions helps in designing electrical components, analyzing electric fields in space, and comprehending the principles of electric force and potential.
