SUMMARY

The discussion focuses on calculating the potential difference (ΔV) between points A and B using the formula V = kq / r. The user derived the potential at points A and B as VA = kq / R and VB = kq / 3R, respectively. The final expression for the potential difference is confirmed as ΔV = 2kq / 3R. The calculations are verified and deemed correct by the community.

Homework Statement

Homework Equations

V = kq / r

The Attempt at a Solution

V_A = k q / r_A
V_B = k q / r_B
r_B = √((√8 * R)² + R²)
= 3 R
V_B = k q / 3R
ΔV = | VA - VB |
= | kq / R - Kq / 3R |
= 2 kq / 3 R
Can somebody check my answer please ?
