3.6109N or 3.6GN

Explanation:

You first want to use the coordinates to calculate a distance between the charges.
d=(x2x1)2+(y2y1)2
The distance between the two charges is 52 meters
This will be your radius when calculating for the electric force. The formula for the electric force is
Fe=Kq1q2r2
where K=9109 and the units for q is in coulombs and the r is in meters.
Fe=(9109)(5)(4)/(52)2
