My only guess is that e is supposed to be a unit vector. Any idea if that is right? If not, is it possible for you to upload an image of the question? You might be omitting a key detail which you do not realise is important.

This is the exact question :" The vector e=1/3i+2/3j+ezk is a unit vector. Find ez?"
The possible answers are 0,1,1/3 and 2/3

Do you know what it means for a vector to have a unit length (i.e. to be a unit vector)?
