Question #12669

minimum number of unequal vectors whose sum is equal to zero is what? and how?

Expert's answer

In general, given two vectors of unequal length, adding them will result in a non-zero vector because in order to have a zero vector sum, the first and second vectors must "cancel out." For example, if you travel left 1 meter, you must travel 1 meter right to return to your initial position.

The minimum is three: three vectors of unequal form a triangle.
