Three Point Charges Are Placed on the X-Axis,as Follows

question 18

Short Answer

Three point charges are placed on the x-axis,as follows.A charge of +2.0 μC is at the origin,a charge of -2.0 μC is at x = 50 cm,and a charge of +4.0 μC is at x = 100 cm.What are the magnitude and direction of the net electrostatic force exerted on the charge at the origin by the other two charges? (k = 1/4πε₀ = 9.0 × 10⁹ N ∙ m²/C²)
