Two capacitors of capacities 2C and C are joined in parallel and charged up to potential V. The battery is removed and the capacitor of capacity C is filled completely with a medium of dielectric constant K. The potential difference across the capacitors will now be:
  1. VK+2
  2. VK
  3. 3VK+2
  4. 3V K

Solution

Now,

VC=2CV+CVKC+2C

=3V K+2
