Four Equal +6

question 14

Short Answer

Four equal +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?
