Q1 of 177 Page 23

If the position vector of a point (–4, –3) be find

Given is the position vector of point (–4, –3).


We know position vector of a point (x, y) is given by, where and are unit vectors in X and Y directions.



Now, we need to find magnitude of i.e. .


Recall the magnitude of the vector is given as



Here, x = –4 and y = –3






Thus, .
