The electrostatic energy of `4 xx 10^(-6)` J is stored in a capacitor at 100 V. What is the charge on the capacitor?

Explanation

To find the charge on the capacitor, we can use the formula for electrostatic energy stored in a capacitor, which is given by:

\[ E = \frac{1}{2} C V^2 \]

Where:
- \( E \) is the electrostatic energy,
- \( C \) is the capacitance,
- \( V \) is the potential difference (voltage).
