​​​For a ball bearing, the fatigue life in millions of revolutions is given by $L=\left(\frac{C}{P}\right)^{n}$, where $\text{P}$ is the constant applied load and $\text{C}$ is the basic dynamic load rating. Which one of the following statements is TRUE?

  1. $n=3$, assuming that the inner racing is fixed and outer racing is revolving
  2. $n=1 / 3$, assuming that the inner racing is fixed and outer racing is revolving
  3. $n=3$, assuming that the outer racing is fixed and inner racing is revolving
  4. $n=1 / 3$, assuming that the outer racing is fixed and inner racing is revolving
