p^{-}=2i^{-}-3j^{-}+k^{-}, q^{-}=i^{-}+j^{-}-k^{-}, If the vectors a^{-} and b^{-} are the orthogonal projections p^{-} on q^{-} and q^{-} on p^{-} respectively, then {a^{-}\timesb^{-}}/{a^{-}.b^{-}}=

Correct Answer is : 2−i+3−j+5−k2

{2i^{-}+3j^{-}+5k^{-}}/{19\sqrt{2}

{2i^{-}+3j^{-}+5k^{-}}/\sqrt{38}
