Four +6.00-µC point charges are at the corners of a square 2.00 m on each side. What is the electric potential of these charges, relative to infinity, at the center of this square? (k = 1/4πε₀ = 8.99 × 10⁹ N ∙ m²/C²)

Question

Quizplus · Accepted Answer

The potential at the center due to each charge is V = kQ/r, where r is the distance from the charge to the center. For a square, r = (√2/2) * side. Total potential is 4 times the potential due to one charge.
