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

question 45

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 electrostatic force on the charge at the origin due to the other two charges? (k = 1/4πε₀ = 9.0 × 10⁹ N ∙ m²/C²)
