Solution

Solution Steps

Step 1: Understanding the Electric Field Unit

The electric field ($E$) is defined as the force ($F$) per unit charge ($q$). Mathematically, this is expressed as:

\[ E = \frac{F}{q} \]

Step 2: Analyzing the Units

The unit of force ($F$) in the International System of Units (SI) is the newton (N), and the unit of charge ($q$) is the coulomb (C). Therefore, the unit of the electric field is:

\[ \frac{\text{newton (N)}}{\text{coulomb (C)}} = \text{N/C} \]

Step 3: Identifying the Correct Option

From the given options, the correct SI unit for the electric field is 1 N/C.

Final Answer

$\boxed{1 \, \text{N/C}}$
