Two vectors that have equal magnitude and point in opposite directions have a sum of zero. (Like <1,0> and <-1,0>, one pointing in the positive x direction and one in negative x direction.

The same idea applies with three vectors. For example, <1,0,0>, <-1,1,0> and <0,-1,0> have a sum of <0,0,0>.

What is the triangle law of vectors?

If three vectors form a triangle , their vector sum is zero.

What are the coplanar vectors in mathematics?

Vectors that sum to zero are coplanar and coplanar vectors sum to zero.

How do you show that that the three vectors are coplanar?

Three vectors are coplanar if they sum to zero. V1 + V2 + V3 = o means the three vectors are coplanar.

He vector sum of three vectors gives a zero resultant what can be orientation of the vectors?

The orientation of the three vectors that sum to zero must be coplanar, contained in the same common plane, including being contained in a common line in a plane.

The vector sum of three vectors gives a resultant equal to zero What can you say about the vectors?

With three vectors spaced 120 degrees apart and with identical magnitudes the vector sum will be 0.

Under what condition the sum of three vectors will be zero?

Three vectors sum to zero under the condition that they are coplanar (lie in a common plane) and form a triangle. If the vectors are not coplanar, they will not sum to zero. Another way of looking at it is that the sum is zero if any vector is exactly equal in magnitude and opposite in direction to the vector sum (so-called resultant) of the remaining two.

Is it is possible to add three vectors of equal magnitude and get zero?

Yes. Vectors contain both magnitude and direction. Graphically three vectors of equal magnitude added together with a zero sum would be an equilateral triangle.

If two vectors have unequal magnitudes can their sum be zero?

No, they cannot sum to zero.

What is the minimum number of vectors with equal magnitudes whose vector sum can be zero?

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

What is the resultant of a group of vectors if drawing them tip to tail produces close figures?

The result is a zero vector. If the sum of the vectors forms a closed figure, the vectors sum to zero.

When the angle between two vectors is equal to zero?

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.

Suppose you have two vectors that have different magnitudes can the vectors sum ever be zero?

No. The largest possible resultant magnitude is the sum of the individual magnitudes.The smallest possible resultant magnitude is the difference of the individual magnitudes.
