Two parallel plate capacitors whose capacities are C and 2 C respectively, are joined in parallel. These are charged by V potential difference. If the battery is now removed and a dielectric of dielectric constant K is filled in between the plates of the capacitor C, then what will be the potential difference across each capacitor ?
- \(\frac{\mathrm{V}}{\mathrm{~K}+2}\)
- \(\frac{2 \mathrm{~V}}{\mathrm{~K}+2}\)
- \(\frac{3 \mathrm{~V}}{\mathrm{~K}+2}\)
- \(\frac{2+K}{3 V}\)
Answer
(C) 3 ~V ~K +2
