What must be true for two vectors to add up to ZERO? Choose all that apply.
1)Their ycomponents must be equal.
2)They must be antiparallel (point in opposite directions).
3) Their xcomponents must be equal.
4)They must be parallel (point in the same direction).
5) They must have equal magnitudes.
6) They must have opposite magnitudes

What is wrong with 1 and 3?
What is wrong with 6 ? 
Henry
All of the following apply: 1 ,2 , 3 ,
5 , 6. 
Damon
No Henry, for example in #1 the components must be opposite, not equal.
