We want to produce a proton with kinetic energy `4.3 xx 10^-15 J`. Through what difference of potential should we accelerate the proton to obtain this kinetic energy assuming that it starts from rest and no other forces are present ?

Explanation

To solve the problem of determining the potential difference required to accelerate a proton to a kinetic energy of \(4.3 \times 10^{-15} \, \text{J}\), we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Given Values:**
- Kinetic Energy (\(K\)) = \(4.3 \times 10^{-15} \, \text{J}\)
- Charge of a proton (\(Q\)) = \(1.6 \times 10^{-19} \, \text{C}\)
