Question

What is the mixed triple product of three vectors?

(a) S.(PxQ)

(b) Sx(PxQ)

(c) S.(P.Q)

(d) Sx(P.Q)

I had been asked this question in an interview.

I'm obligated to ask this question of Dot Product and Cross Product in portion Force Vectors of Engineering Mechanics

Answer 1

Right answer is (a) S.(PxQ)

To explain: It is the scalar expression. It is the dot product of the vector to the vector, which is the result of the cross vector product of two vectors. And if two vectors are held together in the equation by a dot “.”, then the answer which you get is the scalar quantity.
