Answer 2

The charge stored in the capacitor is  $\sqrt2\times 10 \ \mu C.$

Explanation:

Given:

Capacitance of the capacitor , C = 25 pF.

Energy stored in the capacitor , E = 4 J.

We need to know the charge q on the capacitor.

ALSO,

We know energy stored in the capacitor $E=\dfrac{1}{2}\times C\times V^2.$

$q=\sqrt{2\times E\times C$.

Putting all given values we get,

$q=\sqrt{2\times 4\times 25\times 10^{-12}$

$q=10\times \sqrt2 \times 10^{-6}\ C$

$q=\sqrt2\times 10 \ \mu C.$

Therefore, the charge stored in the capacitor is  $\sqrt2\times 10 \ \mu C.$
