It is a vector which denotes the position of a particle at any instant of time, with respect to some reference frame or coordinate system.

**POSITION VECTOR**

It
is a vector which denotes the position of a particle at any instant of time,
with respect to some reference frame or coordinate system.

The position vector of the particle at a point P is given by

Determine the position vectors for the following particles which are located at points P, Q, R, S.

A person initially at rest starts to walk 2 m towards north, then 1 m towards east, then 5 m towards south and then 3 m towards west. What is the position vector of the person at the end of the trip?

*Solution*

As shown in the Figure, the positive x axis is taken as east direction, positive y direction is taken as north.

After the trip, the person reaches the point P whose position vector given by

The displacement direction is south west.
