if is orthogonal to v. then it should satisfy following condition 3x+4y=0 example <4,-3,6555>

tq :),but then the unit vectors?

For two vectors to be orthogonal, they need to have a dot product of 0. So your first vector <3,4,0> will be dotted with . However, you want the unit vectors, so you have to turn into unit vectors. To do that you simply divide the vector by its magnitude. So the unit vector is /x^2+y^2+z^2. Now dotting your two vectors will yield, 3x/(x^2+y^2+z^2) +(4y/x^2+y^2+z^2)=0
