1. The problem statement, all variables and given/known data What is the magnitude of the electric field at a distance of 5.00 ×10−10 m from a radon nucleus? =4.95×1011 N/C What is the magnitude of the force on an electron at that distance? =7.94×10-8 N Now here is where I am getting stuck.. Treating the electron classically, that is, as a point object that can move around the nucleus at reasonably slow speeds, what is the period of the electron's motion? & Again treating the electron classically, how fast it it moving? 2. Relevant equations T=2Pi/omega a=v^2/r f=mr omega^2 3. The attempt at a solution i tried solving for omega by plugging in the force, radius and mass of radon. then square rooting the answer. so ill have omega and then i take 2 pi over it right? for the period.. thats not working. then i tried solving for the velocity by taking the force * radius / mass then square rooting that as well to find the velocity and that is wrong... i dont know where i am going wrong.. any help would be great. thanks!
