In the circuit shown, a potential difference of \[60V\]is applied across AB. The potential difference between the points M and N is:

A)  \[10\,V\]                     

B)  \[15\,V\]

C)  \[20\,V\]                     

D)  \[30\,V\]

Correct Answer: D

Solution :

Charge on capacitor C between MN is \[=60\times \frac{C}{2}=30C.\]             \[\therefore \]     \[{{V}_{MN}}=\frac{30C}{C}=30V\]
