An uncharged parallel plate capacitor having a dielectric of constant \(K\) is connected to a similar air cored parallel capacitor charged to a potential \(V\). The two capacitors share charges and the common potential is \(V'\). The dielectric constant \(K\) is
- A\(\frac{V'-V}{V'+V}\)
- B\(\frac{V'-V}{V'}\)
- C\(\frac{V'-V}{V}\)
- D\(\frac{V-V'}{V'}\)
