A suitble unit for expressing electric field strength is

Options

A. `V//C`
B. `C//m^(2)`
C. `Am`
D. `N//C`

Explanation

To determine a suitable unit for expressing electric field strength, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Electric Field Strength**:
- Electric field strength (E) is defined as the force (F) experienced by a unit positive charge (Q) placed at a point in an electric field.
- Mathematically, this can be expressed as:
\[ E = \frac{F}{Q} \]

2. **Identifying the Units**:
- The unit of force (F) in the International System of Units (SI) is Newton (N).
- The unit of charge (Q) is Coulomb (C).
- Therefore, substituting these units into the formula gives us:
\[ E = \frac{\text{Newton}}{\text{Coulomb}} = \text{N/C} \]

3. **Conclusion**:
- The suitable unit for expressing electric field strength is Newton per Coulomb (N/C).

### Final Answer:
The suitable unit for expressing electric field strength is **Newton per Coulomb (N/C)**.
