![# Electric Potential and Electrostatics: Problem Analysis
A mass has a charge of \( q = 5e \), where \( e \) is the charge on an electron. We will explore various scenarios to understand the electric potential difference created by this charge.
### (a) Determining the Electric Potential \( V(r) \)
**Question:**
Determine the electric potential \( V(r) \) due to the charge at a distance \( r = 0.160 \) cm from the charge.
**Answer:**
\[ V(r) = 4.50 \times 10^{6} \, \text{V} \]
Explanation: This value represents the electric potential at a distance of 0.160 cm from the charge.
### (b) Electric Potential Difference Between Two Points
**Question:**
Determine the electric potential difference (in V) between a point that is \( 5r \) away and this point, that is \( V(5r) - V(r) \).
**Common Mistake:**
\[ \text{Provided Answer: } 7.20 \times 10^{-7} \, \text{V} \]
\[ \text{Note: } Don't forget, we want \( V(5r) - V(r) \) and not \( V(r) - V(5r) \). Try writing your answer in terms of the expression for \( V(r) \) obtained in part (a). \]
### (c) Electric Potential Difference for a Fractional Distance
**Question:**
Determine the electric potential difference (in V) between a point that is \( \frac{r}{5} \) away and this point, that is \( V \left(\frac{r}{5}\right) - V(r) \).
**Common Mistake:**
\[ \text{Provided Answer: } -1.80 \times 10^{-6} \, \text{V} \]
\[ \text{Note: } Don't forget, we want \( V \left( \frac{r}{5} \right) - V(r) \) and not \( V(r) - V \left( \frac{r}{5} \right) \). Try writing your answer in terms of the expression for \( V(r) \) obtained in part (a). \]
### (d) Potential Difference with Proton Replacement
