## Homework Statement

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?

## Homework Equations

T=2Pi/omega

a=v^2/r

f=mr omega^2

## 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.. that's 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 don't know where i am going wrong.. any help would be great.

thanks!
