you'll need at least three. Think of them as being connected. To have a zero resultant, putting the vectors together head to tail should form a closed shape. The first vector can be in any direction. The second vector starts where the first ended, and extends in a different plane. The last vector starts from where the second ended and extends to the beginning of the first vector. The three end up making a triangle, which gives you a zero resultant
If all magnitudes are different, then minimum is three.
Two vectors: no. Three vectors: yes.
1. When the two vectors are parlell the magnitude of resultant vector R=A+B. 2. When the two vectors are having equal magnitude and they are antiparlell then R=A-A=0. For more information: thrinath_dadi@yahoo.com
Two vectors with unequal magnitudes can't add to zero, but three or more can.
No. Three can, but two need to cancel out exactly, meaning they must have the same magnitude in opposite directions.
If all magnitudes are different, then minimum is three.
Two vectors: no. Three vectors: yes.
It is certain that two vectors of different magnitudes cannot yield a zero resultant force.
No.
Two vectors, no; three vectors yes.
If their sum (resultant) is 0, then the magnitude of the resultant must be 0.
-- The minimum magnitude that can result from the combination of two vectors is the difference between their magnitudes. If their magnitudes are different, then they can't combine to produce zero. -- But three or more vectors with different magnitudes can combine to produce a zero magnitude.
Yes, if they are pointing in opposite directions (separated by 180°).
Two vectors having same magnitude but different direction are called equivalent vectors.

Equal vectors are vectors having same direction of action or orientation as well as same magnitude. If two or more vectors have same magnitude but different direction then they cannot be called equal vectors. This shows that direction is important for equal vectors.
Two vectors with unequal magnitudes can't add to zero, but three or more can.
