Question

Suppose that you are holding a pencil balanced on its point. If you release the pencil and it begins to fall, What is the distance rn$r_{\mathrm{n}}\text{r\_n}$ between the point of application of  n⃗ $\overrightarrow{n}\text{n\_vec}$ and the axis of rotation? What is the distance rw$r_{\mathrm{w}}\text{r\_w}$ between the point of application of w⃗ $\overrightarrow{w}\text{w\_vec}$ and the axis?
