Questions
The angle between the two vectors and is
a
45°
b
90°
c
30°
d
60°
detailed solution
Correct option is B
Let A = -2i^+3j^+k^B = i^+2j^-4k^∴ A·B=(-2i^+3j^+k^)·(i^+2j^-4k^)=-2+6-4=0Since, dot product of two vectors is zero, so vectors will be perpendicular (i.e. θ = 90°) to each other.Talk to our academic expert!
