You'll like this; it's very nice! When we say that F is directly promotional to r, that means we can write relate them by an equation similar to this \(F=kr\). Our task here is to find what the value of k is.

But we're already given that \(F=1\) when \(r=3\). So we can write: \(11=k\times 3 \) Now divide both sides by 3, you get \[\frac{11}{3}=k.\]

Now substitute that for k in that equation, and you're done: \[F=\frac{11}{3} r\]
