Two parallel plate capacitors, each of capacitance `40 muF, are connected is series. The space between the plates of one capacitor is filled with a dielectric material of dielectric constant K =4. Find the equivalent capacitacne of the system.

Explanation

To solve the problem of finding the equivalent capacitance of two parallel plate capacitors connected in series, where one capacitor has a dielectric material, we can follow these steps:

### Step 1: Identify the given values
- Capacitance of both capacitors without dielectric, \( C_1 = C_2 = 40 \, \mu F \)
- Dielectric constant for the dielectric material, \( K = 4 \)

### Step 2: Calculate the capacitance of the capacitor with the dielectric
The capacitance of a capacitor with a dielectric is given by the formula:
