#### Answer:

I found:

#### Explanation:

Centripetal force is given as:

We can evaluate the velocity knowing that the object moves of a (linear) distance equal to:

and that the frequency (representing the number of turns in one second) is

So the total liner distance will be:

Using this information into the expression for centripetal force (1) we get:
