Homework Statement
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 by about 0.28 nm. Calculate the electrostatic force between a sodium ion and a chloride ion.
a) magnitude
b) direction
The Attempt at a Solution
e = 1.602 * 10^-19
i think you use this as q1 * q2?
and use the F = k(q1*q2)/r^2
i am not sure how to appropriated this problem
