To find the central angle for the sector representing *Electricity*, we follow these steps:

### Step 1: Calculate the proportion of the salary spent on Electricity.
- The total annual salary is $60,000.
- The amount spent on Electricity is $2,000.

The proportion of the salary spent on Electricity is:

\[
\frac{2000}{60000} = \frac{1}{30}
\]

### Step 2: Calculate the central angle.
The total angle in a circle is 360°. So, the central angle for Electricity is:

\[
\text{Central Angle} = \frac{1}{30} \times 360° = 12°
\]

Thus, the central angle for the sector of Electricity is **12°**.
