What work must be done in carrying an `alpha -` pariclae across a potential difference of 1 volt?

Explanation

To find the work done in carrying an alpha particle across a potential difference of 1 volt, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the charge of the alpha particle**:
An alpha particle consists of 2 protons and 2 neutrons. The charge of a proton is approximately \( e = 1.6 \times 10^{-19} \) coulombs. Therefore, the total charge \( Q \) of the alpha particle is:
\[
Q = 2 \times e = 2 \times (1.6 \times 10^{-19}) = 3.2 \times 10^{-19} \text{ coulombs}
