Question

(C) What is the angle between A = i + ſ and B = î - ſ
(a) 45°
(b) 90°
(c) -45°
(d) 180°​

Answer 1

Answer:

ANSWER

Given that,  

A

=  

i

^

+  

j

^

​  

 

and  

B

=  

i

^

−  

j

^

​  

 

∵  

A

⋅  

B

=0

Since the dot product of the two vectors is zero, it means that the vectors are perpendicular to each other.

Hence, Angle between vectors,  

A

 and  

B

 is 90
