\(\frac{1}{3}(4i + 3j)\)
\(\frac{1}{3}(3i + 4j)\)
\(\frac{1}{5}(3i + 4j)\)
\(\frac{1}{5}(4i + 3j)\)
Correct answer is D
\(\hat {n} = \frac{\overrightarrow{p}}{|p|}\)
where \(\hat {n}\) is the unit vector in the direction of p.
\(|p| = \sqrt{4^{2} + 3^{2}} = \sqrt{25} = 5\)
\(\hat {n} = \frac{1}{5} (4i + 3j)\)
