Question

the angle between two vector A and B theta the value of the triple product vector A•(vectorB×vectorA) is​

Answer 1

it will be 0. The cross product of 2 vectors is always perpendicular to the plane containing the 2 vectors. So now when u further do the dot product the angle btwn the cross product vector and A vector is actually 90degree n as u know that dot product is vector1vector2cos(theta) so since now theta is 90 so ur answer will b 0
