Pоtentiаl due tо pоint-chаrges: Four equаl +6.00-μC point charges are placed at the corners of a square 2.00 m on each side. (k = 1/4πε0 = 8.99 × 109 N ∙ m2/C2) (a) What is the electric potential (relative to infinity) due to these charges at the center of this square? (b) What is the magnitude of the electric field due to these charges at the center of the square?
