Two charges are placed on the x-axis, +8.00 μC at the origin and -10.0 μC at x = 10.0 cm. Define the positive direction as the +x-direction.
Find the electric field E on the x-axis at x = 6.00 cm.
At what point(s) x₀ on the x-axis is the electric field zero? If there are multiple points, enter the x-coordinates as a comma-separated list.
