### Problem Statement:

In the figure, how much charge is stored on the parallel-plate capacitors by the 19.0 V battery? One capacitor is filled with air, and the other is filled with a dielectric for which \( \kappa = 2.70 \); both capacitors have a plate area of \( 9.70 \times 10^{-3} \, \text{m}^2 \) and a plate separation of 1.50 mm.

#### Diagram:

The diagram shows two parallel-plate capacitors \( C_1 \) and \( C_2 \) connected in parallel to a battery of voltage \( V \).

\[ V \]
\[ \vert \]
\[ - \text{C_1} \quad \text{C_2} \]
\[ \vert \]
\[ \]

#### Inputs for Calculation:
- **Voltage of battery, \( V \)**: 19.0 V
- **Dielectric constant, \( \kappa \)** for \( C_2 \): 2.70
- **Plate area, \( A \)** for both capacitors: \( 9.70 \times 10^{-3} \, \text{m}^2 \)
- **Plate separation, \( d \)** for both capacitors: 1.50 mm (or \( 1.50 \times 10^{-3} \, \text{m} \))

#### Solution Steps:

1. **Calculate the capacitance for each capacitor:**

   For \( C_1 \) (filled with air):
   \[
   C_1 = \epsilon_0 \frac{A}{d}
   \]
   where \( \epsilon_0 \) is the permittivity of free space (\( 8.85 \times 10^{-12} \, \text{F/m} \)).
   
   For \( C_2 \) (filled with dielectric \( \kappa = 2.70 \)):
   \[
   C_2 = \kappa \epsilon_0 \frac{A}{d}
   \]

2. **Find the total equivalent capacitance \( C_{\text{eq}} \) for capacitors in parallel:**
   \[
   C_{\text{eq}} = C_1 + C_2
   \]

3. **Calculate the total charge stored using the battery voltage \( V \
