Vector Basics, Unit Vectors & Components

A vector PP has XX and YY components of magnitude 2 units and 4 units respectively. A vector QQ along negative XX-axis has magnitude 6 units. The vector (Q−P)(\mathbf{Q} - \mathbf{P}) will be

Show answer and solution

Answer: (d)

  1. P⃗=2i^+4j^\vec{P} = 2\hat{i} + 4\hat{j}, Q⃗=−6i^\vec{Q} = -6\hat{i}
  2. Q⃗−P⃗=−8i^−4j^=−4(2i^+j^)\vec{Q} - \vec{P} = -8\hat{i} - 4\hat{j} = -4(2\hat{i} + \hat{j})
  3. So the answer is (d).
