Two point charged objects produce an electric force on each other of 6.20 * 10^-2 N. What is the electric force if the distance between increases three times?(adsbygoogle = window.adsbygoogle || []).push({});

I understand that this formula can be used, Fe=(kq1q2)/R^2, but how can you determine K and R from this formula. Any help would be appreciated.
