Question The separation between Na+ and Cl- ions in a molecule is 0.24nm. They are point charges of +q and -q and force of attraction between them is 4.0x10^-19N. a) Get the magnitude of the q Possible Answer: Do I just use Coloumbs law? I got 1.03x10^-14C b) What is the electrical field strength (in magnitude and direction) at the mid-point of the molecule? Possible Answer: Not sure what to do here? I'm thinking maybe its 0 but that would just be too easy. Thanks in advance!?
