Three Point Charges Are Placed on the X-Axis

question 8

Short Answer

Three point charges are placed on the x-axis.A charge of +2.0 μC is placed at the origin,
-2.0 μC to the right at x = 50 cm,and +4.0 μC at the 100 cm mark.What are the magnitude and direction of the electrostatic force that acts on the charge at the origin? (k = 1/4πε₀ =
8.99 × 10⁹ N ∙ m²/C²)
