Question

Find the vector component of the vector with initial point (2, 1) and terminal point (–5, 7).

विकल्प

• 7, 6

• –7, 6

• 5, 6

• –5, 6

Answer 1

–7, 6

Explanation:

Let A(2, 1) be the initial point and B(–5, 7) be the terminal point.

∴ AB = ${\displaystyle (x_2-x_1)\hat{i}+(y_2-y_1)\hat{j}}$

= ${\displaystyle (-5-2)\hat{i}+(7-1)\hat{j}}$

= ${\displaystyle -7\hat{i}+6\hat{j}}$

The sclar components are –7 and 6.
