Question

Two vectors A and B lie in X-Y plane. The vector B is perpendicular to vector A. If A = i ˆ + j ˆ , then B may be?

Answer 1

Answer:

since vector A and B are perpendicular so A.B =0

vector B may be i^-j^or -i^+j^

Answer 2

Answer:

Step-by-step explanation:

Given that A=i+j and A is perpendicular to B, then B will be

So, as we know that A.B=0

B= 1= -i+j ,2= i-j
