Let Q amount of charge flows through the M N branch. V=60 V =(Q/2 C)+(Q/C)+(Q/2 C)=2 (Q/C) or Q=30 C Potential difference between M and N =(Q/C)=(30 C/C) V =30 V

Q. In the circuit shown in figure, 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

Let $Q$ amount of charge flows through the $MN$ branch.
$V = 60 V = \frac{Q}{2 C} + \frac{Q}{C} + \frac{Q}{2 C} = 2 \frac{Q}{C}$ or
$Q = 30 C$
Potential difference between $M$ and $N$
$= \frac{Q}{C} = \frac{30 C}{C} V = 30 V$

Q. In the circuit shown in figure, a potential difference of 60V is applied across AB. The potential difference between the points M and N is
