Equivalent capacitor in circuit A'MNB' is (C/2) Charge on capacitor C between MN is 60× (C/2)=30 C <img class="img-fluid question-image" alt="Solution" src="https://cdn.tardigrade.in/q/nta/p-nbemwcf4mu33.png" /> ∴ VMN=(30 C/C)=30V

Q. In the circuit shown, a potential difference of $60 V$ is applied across $A B$ . The potential difference between the points $M$ and $N$ is

$10 V$

$15 V$

$20 V$

$30 V$

Equivalent capacitor in circuit $A^{'} MN B^{'}$ is $\frac{C}{2}$
Charge on capacitor $C$ between $MN$ is $60 \times \frac{C}{2} = 30 C$

$∴ V_{MN} = \frac{30 C}{C} = 30 V$
