The angle between $\to A$ and $\to B$ is $θ$ .The value of the triple product $\to A . \to B \times \to A$ is

Open in App

Solution

The resultant vector of the cross product of two vectors is perpendicular to both of them
Let A X B =C
Then A.C=AC cos 90 degree.(As C is perpendicular to A and B)
Hence A.C=ACX0=0
