The electric potential \( V \) at a distance of 1.00 cm from a proton can be calculated using the formula \( V = \frac{k \cdot q}{r} \), where \( k \) is Coulomb's constant (\( 8.99 \times 10^9 \, \text{N m}^2/\text{C}^2 \)), \( q \) is the charge of the proton (\( 1.60 \times 10^{-19} \, \text{C} \)), and \( r \) is the distance from the charge. The potential difference \( \Delta V \) between two points at 1.00 cm and 2.00 cm from the proton can be determined by calculating the electric potentials at both distances and finding their difference. This discussion emphasizes the application of the electric potential formula for point charges in electrostatics.
