Question :
Two vectors are of identical magnitude have their dot product as 32 and both are of magnitude 4 then they are inclined at an angle of—.
(A) 60°
(B)π/3
(C) cos-1(2)
(D)no such vectors exist
Formula :
Cross product of two vectors
Where : angle between two vectors.
Solution :
Let the two vectors be
32 = (4)(4)cos
32 = 16cos
cos = 2
Since cosine function lies between [-1,1]
No such vectors are possible .
Option :
The correct option is option(D).
