Question

Find the scalar and vector components of the vector with initial point (2,1) and terminal point (-5,7).

Answer 1

The vector with the initial point P(2,1) and Q(-5,7) can be given by,
$\overrightarrow{PQ}$ = $(-5-2)\hat i+(7-1)\hat{j}$
⇒$$\overrightarrow{PQ} = $-7\hat i+6\hat{j}$
Hence, the required scalar components are -7 and 6 while the vector components are $-7\hat i$and $6\hat{j}$.
