Question

why resultant of three non co planar vectors can never be zero
​

Answer 1

Answer:

This is because three vectors are not in the same plane but when we resolve their rectangular component, they do not cancel each other therefore resultant is not zero.

Explanation:

1st 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.
