What is the Minimum number of vectors with unequal magnitudes whose vector sum can be zero?

-- A singe vector with a magnitude of zero produces a zero resultant.-- Two vectors with equal magnitudes and opposite directions produce a zero resultant.


Two vectors have the length v1 is 3.5km and v2 is 4 kmwhat are the maximum and minimum magnitudes of their vector sum?

3.5+4.0 and 4.0-3.5


Why a unit vector is aone type of vector but a vector is not a unit vector?

A unit vector is a vector whose magnitude is one. Vectors can have magnitudes that are bigger or smaller than one so they would not be unit vectors.


What is the angle between two vectors if their sum is to be maximum?

The resultant vector has maximum magnitude if the vectors act in concert. That is, if the angle between them is 0 radians (or degrees). The magnitude of the resultant is the sum of the magnitudes of the vectors.For two vectors, the resultant is a minimum if the vectors act in opposition, that is the angle between them is pi radians (180 degrees). In this case the resultant has a magnitude that is equal to the difference between the two vectors' magnitudes, and it acts in the direction of the larger vector.At all other angles, the resultant vector has intermediate magnitudes.


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.


Can the magnitude of the resultant of two vector be greater than the sum of magnitudes of individual vectors?

No.


Can the magnitude of a resultant vector be greater than the sum of individual vectors?

The resultant vector IS the sum of the individual vectors. Its magnitudecan be the sum of their individual magnitudes or less, but not greater.


Can the sum of the magnitudes of two vectors ever b equal to the the sum of these two vectors?

Not really. The sum of the magnitudes is a scalar, not a vector - so they can't be equal. But the sum of the two vectors can have the same magnitude, if both vectors point in the same direction.


Can the sum of two vectors of unequal magnitudes be a zero vector?

The sum of two unequal vectors can not be zero, because we can get minimum magnitude of two vectors when they are in opposite direction and can only get zero magnitude when they are equal in magnitude.................................... Answered by: SAJJAD AHMED(bfps doha Qatar)


Explain what is meant by a concurrent vectors?

A vector has 2 components - it's magnitude and direction. Concurrent vectors are 2 vectors that have the same direction but may have different magnitudes.


Can A plus B equal zero when A and B have nonzero magnitudes?

If 'A' and 'B' are vectors, and their magnitudes are equal, andtheir directions are opposite, then their vector sum is zero.


What are different conditions that could make vector product zero?

First of all, you have to define what you mean by "vector product".-- The "dot product" is zero if the vectors are perpendicular, regardless of their magnitudes.-- The "cross product" is zero if the vectors are collinear or opposite, regardless of their magnitudes.-- Perhaps when you say "product", you mean the "result" of two vectors, whicha mathematician or physicist would cal their "sum".The sum of two vectors is zero if their magnitudes are equal and their directionsdiffer by 180 degrees.An infinite number of other possibilities exist for a sum of zero, depending on themagnitudes and directions of two vectors.
