In solid sodium chloride (table salt), chloride ions have one more electron than they have protons, and sodium ions have one more proton than they have electrons. These ions are separated at about 0.28 nm. Calculate the electrostatic force between the sodium ion and the chloride ion.

What I did was the following:
F=k|q1*q2|/r^2

F=8.99e9(1.602e-19*1.602e-19)/(2.8e-10)^2
F= 2.94e-9 N

But that's not the answer. Can someone please tell me what I'm doing wrong.

I don't see anything wrong with it.
