CBSE Class 11-science Answered
If A vector and B vector = 0 vector and A vector . B vector = 0, does it imply that one of the vectors A vector or B vector must be a null vector?

Expert Answer
A vector. B vector = ABcosΘ
We know that cos 90º= 0
So, even if the angle between A vector and B vector is 90º or 270º , A vector. B vector = 0
So, it is not necessary for A vector and vector B to be zero.
If Θ= 90°,270°
Then, A vector. B vector= 0
