Quick Answer: What Is The Minimum Number Of Vectors With Equal Magnitudes?

What quality is a vector quantity?

Vector, in physics, a quantity that has both magnitude and direction.

It is typically represented by an arrow whose direction is the same as that of the quantity and whose length is proportional to the quantity’s magnitude.

Although a vector has magnitude and direction, it does not have position..

Which of following is not a vector quantity?

Answer: Speed is not a vector quantity. It has only magnitude and no direction and hence it is a scalar quantity.

What is the cross product of equal vectors?

Since two identical vectors produce a degenerate parallelogram with no area, the cross product of any vector with itself is zero… Applying this corollary to the unit vectors means that the cross product of any unit vector with itself is zero.

Can two vectors have different magnitudes equal?

Can two vectors of unequal magnitude? Yes, two vectors of equal magnitude that are pointing in opposite directions will sum to zero. Two vectors of unequal magnitude can never sum to zero. If they point along the same line, since their magnitudes are different, the sum will not be zero.

Can we multiply a vector by a real number?

Multiplication of Vectors by Real Numbers – Multiplication of a vector A with a positive number k only changes the magnitude of the vector keeping its direction unchanged.

Is the vector sum of the unit vectors i and Ja unit vector if no can you multiply this sum by a scalar number to get a unit vector?

Solution. No, the vector sum of the unit vectors and is not a unit vector, because the magnitude of the resultant of and is not one. Yes, we can multiply this resultant vector by a scalar number to get a unit vector.

At what angle between two vectors will their resultant have a minimum amount?

180 degreesFor the magnitude of the resultant of two forces to be minimum, the angle between the two vectors that represent the forces should be 180 degrees. In other words the forces should be in the opposite direction.

What is the minimum number of unequal vectors to result into a null vector explain with diagram?

What is the minimum number of unequal vectors to result into a null vector? The answer is 1 (or 0), or 2, or 3. First, there is the trivial solution: the null vector by itself clearly “sums” to the null vector.

What is the minimum number of vectors in different planes?

Four vectors in different planes may give zero resultant.

When two vectors A and B are added the magnitude of the resultant vector is always?

When two vectors →A and →B of magnitudes a and b respectively are added, the magnitude of resultant vector is always. Join the 2 Crores+ Student community now!

Can you add three vectors of equal magnitudes and get zero?

Yes, it is possible to add three vectors of equal magnitudes and get zero.

What is maximum number of components into which a vector can be split?

A vector can be split into infinite components (but only 3 orthogonal ones)

Does it make a sense to call a physical quantity a vector when its magnitude is zero?

Does it make sense to call a physical quantity a vector when its magnitude is zero ? Yes,null vector has a definite physical significance.

What is the minimum number of non zero vectors?

answer : Almost 3 numbers of non zero vectors in different planes can be added to give zero resultant. Reason : 3 non zero vectors in different planes will form a triangle which will result in zero resultant.

What is an unequal vector?

Yes. Any two vectors are said to be “equal vectors” , when they have same magnitude and same direction. In all other cases apart the above one case , they are called “unequal vectors.” So, If two vectors have same magnitude but different directions , they are called unequal vectors.

What is the minimum number of vectors with unequal magnitudes?

threeAssertion: The minimum number of vectors of unequal magnitude required to produce zero resultant is three. Reason: Three vectors of unequal magnitude which can be represented by the three sides of a triangle taken in order, produce zero resultant.

What is the minimum number of coplanar vectors that have different magnitude?

According to the Triangle Law of vector addition, a minimum of three vectors are needed to get zero resultant. So we can say that a minimum of 3 coplanar vectors is required to represent the same physical quantity having different magnitudes that can be added to give zero resultant.

What are the minimum number of unequal forces whose vector sum is zero?

threeWe know that only triangle is closed figure of minimum side, Sides of triangle represent vector, So the minimum number of unequal vectors whose vector sum can be zero is three.
