Electric potential
V = kq/r
Where: V = volume (m³) / potential difference (V), k = spring constant (N/m) / Coulomb constant, q = charge (C), r = radius / distance (m)
Solved example
Given: k = 7, q = 5, r = 10

- Formula: V = k·q/r
- Substitute the values: V = 5·7/10
- Result: V = 3.5 V
Answer: V = 3.5 V
