The force per unit charge is known as

Options

A. electric flux
B. electric field
C. electric potential
D. electric current

Answer

To solve the question "The force per unit charge is known as," we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Concept**:
- The question asks for the term that describes the force experienced by a charge per unit of that charge. This is a fundamental concept in electrostatics.

2. **Defining Electric Field**:
- The electric field (E) is defined as the force (F) experienced by a unit positive charge (Q) placed in the field. Mathematically, this can be expressed as:
\[ E = \frac{F}{Q} \]
- Here, \(E\) is the electric field, \(F\) is the force, and \(Q\) is the charge.

3. **Identifying the Correct Term**:
- From the definition above, we can conclude that the term for force per unit charge is the electric field intensity.

4. **Reviewing Other Options**:
- The question provides multiple options. We can briefly define them to ensure clarity:
- **Electric Flux**: This is related to the number of electric field lines passing through a surface and is given by the formula \( \Phi_E = E \cdot A \cdot \cos(\theta) \).
- **Electric Potential**: This is the work done per unit charge in bringing a charge from infinity to a point in the electric field, denoted as \(V = \frac{W}{Q}\).
- **Electric Current**: This is the rate of flow of charge, defined as \(I = \frac{dQ}{dt}\).

5. **Conclusion**:
- After analyzing the definitions, we conclude that the force per unit charge is known as **Electric Field Intensity**.

### Final Answer:
The force per unit charge is known as **Electric Field Intensity**.
