## More on Relative Vectors and Velocities

If a particle North or South, East or West of another particle, then we can write down conditions that the position vectors must satisfy.

If the particle A is North of particle B thenand

If the particle A is East of particle B thenand

Suppose then that

When A is North of B, the(or) components are equal:

When A is East of B, the(or) components are equal:
