1. The problem statement, all variables and given/known data Calculate the spring constant of a spring with an electron mass at itsend and the frequency 4.9X10^14 Hz. mass of electron: 9.11X10^-31 g 2. Relevant equations F=kx k=mg/x 3. The attempt at a solution Since i know the frequency, i can get the period, but where i am stuck is how to turn the period into an x value that i can use to determine the value of k. should i be using coulomb's law for this?
