Problem

Two condensers

A

and

B

each having slabs of dielectric constant

K = 2

are connected in series. When they are connected across

230 \text{ V}

supply, potential difference across

A

130 \text{ V}

and that across

B

100 \text{ 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?
