Is it possible to get zero vector as a resultant of three non-coplanar vectors ? Is the same possible in case of four non-coplanar vectors?

Explanation

No, three non-coplanar vectors cannot ad up to given zero resultant because for non-coplanar vectors the resultant of the two vectors will not lie in the plane of third vector , and so the resultant cannot cancel the third vector to given null vector . It can be possible in case of four vectors .
