Question
The vector with initial point P (2, -3, 5) and terminal point Q(3, -4, 7) is
✓
Answer
(b) $\hat{i}-\hat{j}+2 \hat{k}$ Explanation: To find the vector we need to find the $\overrightarrow{P Q}$ $=3 \hat{i}-4 \hat{j}+7 \hat{k}-(2 \hat{i}+3 \hat{j}-5 \hat{k})$. Hence, the vector formed by above points is with the following $(1,-1,2)$.
