Question

A +2.00-nC point charge is at the origin, and a second-5.00-nC point charge is on the x-axis at x = 0.8m. A) Findthe electric field(magnitude and direction) at each of thefollowing points on the x axis. i) x-2.00m; ii) x=1.2m iii) x= -0.2m. b) Find the net electric force that the two chargeswould exert on an electron placed at each point in part a).
