As we have learned

Vector Triple Product -

\vec{a}\times \left ( \vec{b} \times \vec{c}\right ) is a vector perpendicular to \vec{a} and \left ( \vec{b} \times \vec{c}\right )

- wherein

Fig 11

 

 IN (A ), (B) and (C) vector has direction perpendicular to both \vec c \: \: and \: \: (\vec a \times \vec b)
