Two condensers `A` and `B` each having slabs of dielectric constant `K = 2` are connected in series. When they are connected across `230 V` supply, potential difference across `A` is `130 V` and that across B is `100 V`. If the dielectric in the condenser of smaller capacitance is replaced by one for which `K = 5`, what will be the values of potential difference across them?

Explanation

To solve the problem step by step, we will analyze the capacitors A and B connected in series and how the change in dielectric affects the potential difference across them.

### Step 1: Understand the relationship between capacitance and dielectric constant
The capacitance \( C \) of a capacitor with a dielectric is given by:
\[ C = K \cdot C_0 \]
where \( K \) is the dielectric constant and \( C_0 \) is the capacitance without the dielectric.
