Question

find the vector in the direction of displacement of a 3 kilometres towards north​

Answer 1

Answer:

3 units towards north

Explanation:

A vector is the directional representation of some quantity. Since nothing more than just the displacement magnitude and direction is mentioned, I guess you want the vector representation. In that case, the vector will have 3 units ( since 3 km is magnitude ) as per a determined scale, and the arrow will point towards north, thereby representing the north direction.
