The magnitude of the electrostatic force between two identical ions of mass 1.224×10-25 kg that are separated by a distance of 6.50 nm is 1.770×10-9 N. What is the charge of each ion? Calculate the electric field at the site of each ion due to the other ion's presence. If the ions are free to move calculate the initial acceleration.
