Answer:
B) diagram (2)
Explanation:
As we know by the triangular law of addition of two vectors if two vectors are joined head to tail then the third vector in reverse order which will complete the triangle will be given as resultant of the two vectors
so here if A and B are two vectors which are perpendicular to each other then they must be added head to tail then the resultant vector must be in reverse order which will complete the triangle
So it must be
