If the charge on a capacitor is increased by 2 C, the energy stored in it increases by 44%. The original charge on the capacitor is (in C)

Options

A. 10
B. 29
C. 30
D. 40

Explanation

To solve the problem, we need to find the original charge \( Q \) on a capacitor given that increasing the charge by 2 C results in a 44% increase in the energy stored in the capacitor.

### Step-by-Step Solution:

1. **Understanding the Energy Stored in a Capacitor:**
The energy \( U \) stored in a capacitor is given by the formula:
\[
U = \frac{Q^2}{2C}
