Consider the vectors`oversetrarra=2overset^^i-3overset^^j+overset^^k" and "oversetrarrb = overset^^i+overset^^j-2overset^^k`. Find the projection of `oversetrarra " on "oversetrarrb`

Explanation

The projection of `veca "on" vecb "is" (veca.vecb)/(|vecb|)`
`=(-3)/sqrt6=(-3)/(sqrt2 sqrt3)=-sqrt(3//2)`
