Read Detailsa. Two identical point charges are separated by a distance r and exert an electric force on each other. Suppose the distance between the charges is increased to 2r. Explain how the magnitude of the electric force changes. b. Three point charges are fixed along a horizontal line as shown below. q₁ = +4.0 μC q₂ = −2.0 μC q₃ = +6.0 μC ●—————-●—————-● 0.30 m 0.20 m The charges remain stationary. Determine the net force acting on q1. State both the magnitude and the direction. (k = 9×10^9 Nm^2/C^2.)
