Question

how do you deduse that two vector are perpendicular​

Answer 1

Answer:

If two vectors →A and →B are perpendicular to each other than their scalar product →A. →B = O because cos 90° = 0. Then the vectors →A and →B are said to be mutually orthogonal

Answer 2

Answer:

If two vectors →A and →B are perpendicular to each other than their scalar product →A. →B = O because cos 90° = 0. Then the vectors →A and →B are said to be mutually orthogonal..
