can three non-coplanar vectors give zero resultant ? why?
When three vectors are in same plane then their resultant is zero.
First we take two vectors , the resultant of the these two vectors is equal in magnitude of the third vector but directed in opposite direction.
But when these three vectors are not in the same plane , when we resolve their rectangular component, they do not cancel each other therefore resultant is not zero.
