With equal angles between them - which in this case results in 360° / 3 = 120° separation between the angles.
Imagine a triangle with all the sides of different length. If you walk around it, you still end up in the same place.
Take each side of this triangle to be a vector with length of the side and direction of your movement. Each vector starts at the end of previous one, which is how we add vectors - they don't even have to start at the end of each other actually, because for every set of vectors it can be easily arranged.
Since you end up in the same place where you started, the total displacement is zero and so the sum of unequal vectors can be zero.
If the three vectors have equal magnitudes, then they should be arranged symmetrically around
the 'compass', so that the angle between each set of two neighbors is 120 degrees. Then their
resultant is zero.
Answer2:
Form a triangle with the three vectors, this would be a equilateral triangle.
Not strictly. When you say two "equal" vectors, then technically you're saying that
their magnitudes and their directions are equal, and those can't combine to form a
zero resultant.
However, if you have two vectors with equal magnitudes but not necessarily equal
directions, then they'll add to give a zero resultant if you simply make their directions
exact opposites.
Yes. For example, in a single dimension, you can have vectors (1), (2), and (-3), which add up to zero. Similarly in two dimensions - just set the second coordinate to zero. But the three vectors need not be colinear; the sides of any triangle can be replaced by vectors, which add up to zero.
Yes. The only requirement is that the forces balance in three dimensions. This can include any number of unequal forces greater than 2.
Yes, they must have th same scalar value, but opposite direction (the vectors a and -a are different, yet their sum is 0)
Sure. Simply distribute them uniformly around the point at which they act.
In other words, the directions of each two vectors are 120 degrees apart.
yes, they can, as long as they are in different directions
They can. They just need to balance.
No. The tenth vector would have to be matched by one equal and opposite vector to yield a zero resultant, or by multiple vectors in the second plain collectively yielding a zero resultant for that plane. It would be possible, for example, for 8 vectors to be on the same plane and two on a different plane to give a zero resultant.
Thee direction of the two vectors.
Yes. This will happen if the two vectors are at an angle of 120 degrees.
if you add the vectors magnitude and equal to resultant the angle between them is 0
Yes. A vector has magnitude and direction. If the vectors have equal magnitude and directly opposite directions their sum will be zero.
If they are equal in magnitude but act in opposite directions.
No. The tenth vector would have to be matched by one equal and opposite vector to yield a zero resultant, or by multiple vectors in the second plain collectively yielding a zero resultant for that plane. It would be possible, for example, for 8 vectors to be on the same plane and two on a different plane to give a zero resultant.
Let two equal magnitude vectors be 'X'.. Then, resultant=1.414X
Thee direction of the two vectors.
Two - if you add two vectors of equal magnitude but in opposite directions, the resultant vector is zero.
The smallest resultant of two vectors is the sum of two equal vectors which make an angle of 180 degrees among each other.
Yes - if the vectors are at an angle of 60 degrees. In that case, the two vectors, and the resultant, form an equilateral triangle.Yes - if the vectors are at an angle of 60 degrees.

The only way that two vectors add up to zero is if they have equal magnitude and opposite direction. If the magnitudes are not equal then no, they cannot give a zero resultant.
Take any three vectors in a plane which, when placed end-to-end form a triangle. The resultant of the three vectors will be zero.
Yes. This will happen if the two vectors are at an angle of 120 degrees.
Yes. If the two vectors are two sides of an equilateral triangle, then the resultant is the third side and therefore equal in magnitude.
if you add the vectors magnitude and equal to resultant the angle between them is 0
