From the diagram above, which of the following represents the vector V in component form?

  • A \(-5\sqrt{3} i + 5j\)
  • B \(3i + 3\sqrt{3}j\)
  • C \(i + 2\sqrt{3}j\)
  • D \(-2\sqrt{3}i - j\)

The correct answer is B. \(3i + 3\sqrt{3}j\)

\(V = V\cos \theta i + V\sin \theta j\)

\(6N = 6 \cos 60 i + 6 \sin 60 j\)

= \(3i + 3\sqrt{3} j\)
