#### Answer:

I found:

#### Explanation:

Centripetal force is equal to mass time centripetal acceleration:

where:

Now:

Angular Velocity

in this case the distance will be the circumference of

But period is related to frequency

But we want a Linear velocity!

We simply introduce the radius into the

The centripetal force will then become:
