A +2.00nC point charge is at the origin, and a second -5.00nC point charge is on the x-axis at x = 0.800m.

Find the direction of the electric field at x = 1.20m on the x-axis.

negative x direction?
x=1.2 , is closer to the negative charge at x=.8
The other charge is further away and smaller
the impact of the the charge at the origin decreases at 1/(r^2) too
