A vectorPhas X and Y components of magnitude 2 units and 4 units respectively. A vectorQalong negative X-axis has magnitude 6 units. The vector(Q – P)will be

Options:

Answer:

Solution:

Accordingly, to question, vectorsPandQcan be written as
$P = 2 \hat{i} + 4 \hat{j}$
and $Q = - 6 \hat{i}$
$∴ Q - P = - 6 \hat{i} - (2 \hat{i} + 4 \hat{j})$
$= - 8 \hat{i} - 4 \hat{j} = - 4 (2 \hat{i} + \hat{j})$
