the vector perpendicular to both vectors is obtained by doing the cross product of the two vectorsi.e (i-j+k)×(-i+j+k)=(−2i−2j)
and the unit vector is =(1/8)1/2(-2i-2j)

to find the perpendicular vector .first take the cross product of the given 2 vectors.
ie;(i-j+k)x(-i+j+k)= -2i-2j
unit vector is=vector/magnitude of vector
                    =(-2i-2j)/8^1/2
