Find the unit vectors perpendicular to the vectors. 2hati-3hatj+hatk,-hati+2hatj-hatk.

Answer»

SOLUTION :
=`hati(3-2)-HATJ(-2+1)+hatk(4-3)`
= `hati+hatj+hatk`
`|VECAXXVECB| = sqrt3`
If `hatn` is the unit VECTOR perpendicular to `veca` and `vecb` then.
`hatn = +-(vecaxxvecb)/|vecaxxvecb| = +-(hati+hatj+hatk)/sqrt3`.
