When the angle between two vectors is zero ... i.e. the vectors are parallel ... their sum is a vector in thesame direction, and with magnitude equal to the sum of the magnitudes of the two original vectors.

Two is the minimum number of vectors that will sum to zero.

They need equal magnitudes and opposite directions.

In order for two vectors to add up to zero:-- their directions must be exactly opposite-- their magnitudes must be exactly equal

Their sum can be zero only if their magnitudes are equal and their directions are exactly opposite.

The minimum number of vectors with unequal magnitudes whose vector sum can be zero is two. These vectors must have magnitudes and directions that cancel out when added together to result in a zero vector sum.

Two is the minimum number of vectors that will sum to zero.

They need equal magnitudes and opposite directions.

Yes, two vectors of different magnitudes can be combined to give a zero resultant if they are equal in magnitude but opposite in direction. For three vectors to give a zero resultant, they must form a closed triangle or meet at a common point where the sum of the vectors equals zero.

0=v1+v2 means the magnitudes are zero or equal and opposite.

Their magnitudes are exactly equal, and their directions are exactly opposite.

No, the magnitudes of the sum of two vectors are generally greater than or equal to the sum of the magnitudes of the individual vectors. The triangle inequality states that the sum of the lengths of any two sides of a triangle must be greater than the length of the remaining side, which applies to vector addition as well.

The magnitudes of two vectors are added when the vectors are parallel to each other. In this case, the magnitude of the sum is equal to the sum of the magnitudes of the two vectors.

Yes, two vectors with different magnitudes can be combined to give a zero resultant if they are in opposite directions. However, it is not possible for three vectors with different magnitudes to give a zero resultant because they must have specific magnitudes and directions to cancel each other out completely.

Their sum can be zero only if their magnitudes are equal and their directions are exactly opposite.
