<img class="img-fluid question-image" alt="Solution" src="https://cdn.tardigrade.in/q/nta/p-kzxbn8esfeli.png" /> VA-VN=(10 × C/C + (C)3)=(30 C/4 C)= text7.5 VA-0=7.5 VA=7.5 V

Q. The potential at point $A$ , in the circuit, is (Point $N$ is grounded, i.e. the potential of that point is zero.)

$10 V$

$7.5 V$

$5 V$

$2.5 V$

$V_{A} - V_{N} = \frac{10 \times C}{C + \frac{C}{3}} = \frac{30 C}{4 C} = 7.5$
$V_{A} - 0 = 7.5$
$V_{A} = 7.5 V$

Q. The potential at point A , in the circuit, is (Point N is grounded, i.e. the potential of that point is zero.)

10V

7.5V

5V

2.5V
