Two identical parallel plate air capacitors are connected in series to a battery of emf V. If one of the capacitor is completely filled with dielectric material of constant K, then potential difference of the other capacitor will become

B. `(KV)/(K+1)`
C. `(K-1)/(KV)`
D. `(V)/(K(K+1))`

Correct Answer - B
`C_(1)=C_(air)C_(2)=C_(m).C_(air)=C_(1)K`
`V_(1)=((C_(2))/(C_(1)+C_(2)))V=((C_(1)K)/(C_(1)+C_(1)K))V`
`V_(1)=((K)/(1+K))V.`
