Correct Answer: Option C
Explanation:
The unit vector \(\hat{n} = \frac{\overrightarrow{r}}{|r|}\)
\(\hat{n} = \frac{-5i + 12j}{\sqrt{(-5)^{2} + (12)^{2}} \)
= \(\frac{-5i + 12j}{13} \)
The unit vector \(\hat{n} = \frac{\overrightarrow{r}}{|r|}\)
\(\hat{n} = \frac{-5i + 12j}{\sqrt{(-5)^{2} + (12)^{2}} \)
= \(\frac{-5i + 12j}{13} \)
