Quick Answer: What Are The Minimum Number Of Unequal Forces Whose Vector Sum Is Zero?

What happens when we multiply a vector by 2?

When a vector is multiplied by {-2}, the resultant vector is in opposite direction and the magnitude doubles..

What is the minimum number of vectors in different planes?

Minimum number of non-equal vectors in a plane required to give zero resultant is three.

What is the minimum number of vectors with equal magnitudes?

2Minimum number is 2, because 2 vectors of equal magnitude in opposite directions give zero resultant.

Does it make 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.

Is the division of vectors defined?

You can define division of vectors, but as multiplication and division are related operations, you can only do so by choosing a definition of multiplication that allows it. … For two vectors a and b, the dot product a⋅b tells us how much the two vectors are parallel.

Are the magnitude and direction of AB same as that of BA?

Are the magnitude and direction (A-B) same as that of (B-A)? The magnitude of (A – B) and (B -A) will be same but the direction will be opposite.

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)

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

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

What is the minimum number of unequal vectors that can give zero?

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 least number of unequal non zero vectors that can be added to give a resultant equal to zero?

threeWell the answer is three. Clearly two vectors that are unequal can’t sum to zero and by polygon law of addition of vectors, you know 3 or more vectors can be summed to zero. So minimum is 3. Originally Answered: What is the minimum number of vectors in different magnitude can be added to give a zero resultant?

What is angle between p q and p q?

P*Q is a vector perpendicular to the plane of P and Q. Now any vector in the plane of P and Q can be expressed as a linear combination of P and Q. Here P + Q is also a linear combination of P and Q. So P + Q is also perpendicular to P*Q .So, angle between them is 90 degrees.

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.

Can three vectors lying in a plane give zero resultant?

The resultant of the two vectors lie in the same plane. Hence, three vectors in single plane cannot give the resultant zero. … Here, since the three vectors do not lie in the same plane, the resultant of the two cannot be in opposite direction of the third, hence resultant can not be zero.
