Vector Basics, Unit Vectors & Components

Let A⃗\vec{A} and B⃗\vec{B} be two non-zero vectors of different magnitude. Which one of the following is the correct equation?

Show answer and solution

Answer: (c)

  1. Vector addition is commutative: A⃗+B⃗=B⃗+A⃗\vec{A} + \vec{B} = \vec{B} + \vec{A}.
  2. (a) is wrong since A⃗⋅B⃗=+B⃗⋅A⃗\vec{A} \cdot \vec{B} = +\vec{B} \cdot \vec{A}; (b) is wrong since A⃗×B⃗=−B⃗×A⃗\vec{A} \times \vec{B} = -\vec{B} \times \vec{A}; (d) is wrong since A⃗−B⃗=−(B⃗−A⃗)\vec{A} - \vec{B} = -(\vec{B} - \vec{A}).
  3. So the answer is (c).
