Three +30-μC Point Charges Are at the Three Corners of a a Square

question 6

Short Answer

Three +3.0-μC point charges are at the three corners of a square of side 0.50 m.The last corner is occupied by a -3.0-μC charge.Find the magnitude of the electric field at the center of the square.(k = 1/4πε₀ = 8.99 × 10⁹ N ∙ m²/C²)
