Question: a singly charged lithium ion li1 ie a lithium atom...

A singly charged lithium ion (Li+1, i.e. a lithium atom missing one electron) is located at the origin of a cartesian coordinate system. A triply charged nitrogen ion (N-3 , i.e. a nitrogen atom with three extra electrons) is located on the x-axis at x = 1.50 nm. What is the electric field at the point on the y-axis at y = 2.00 nm? Give your answer in component form.
