Can the magnitude of a vector has negative value?

can a magnitude of a vector has negative value?


Can the magnitude of a vector be negative?

No, the value can't be negative because magnitude of a vector is just how long it is regardless of its direction. :-)


Can the magnitude of a vector have a negative value?

The magnitude of a vector is always treated as non negative and the minus sign indicates the reversal of that vector through an angle of 180 degree.


What is different between negative vector and null vector?

A null vector has no magnitude, a negative vector does have a magnitude but it is in the direction opposite to that of the reference vector.


Can the magnitude of a vector have a negative vector?

No because magnitude is like length and you cannot have negative length


What is the magnitude of vector a?

It is the numerical value of the vector.


Can scalar be a negative number?

Yes, a scalar can be a negative number. For instance: c<x₁,x₂> = <cx₁,cx₂> such that <x₁,x₂> is a vector. Let c = -1 for instance. Then, we have this vector: <-x₁,-x₂> Compared to <x₁,x₂>, <-x₁,-x₂> has negative signs. In physics and mathematics, if we multiply the vector or something by a negative value scalar, then the direction of the vector is reversed, and the magnitude stays the same. If the magnitude increases/decreases, and the direction of the vector is reversed, then we can multiply the vector by any negative non-1 scalar value.


Can a vector have a negative value?

A vector is characterized by a magnitude, direction and sense of direction. If you are referring to the magnitude of a vector, it cannot be negative because of the way the magnitude is calculated. For example, vector F has components Fx and Fy. The magnitude of F is (Fx^2+Fy^2)^(1/2)However, you could see something like -F. What you are really looking at is multiplying a vector, F by -1. What this means is that -F has the same magnitude and line of action as F, but has an opposite direction as F.


What does it mean to find the magnitude of a vector?

The magnitude of a vector is a geometrical value for hypotenuse.. The magnitude is found by taking the square root of the i and j components.


What is null vector?

NULL VECTOR::::null vector is avector of zero magnitude and arbitrary direction the sum of a vector and its negative vector is a null vector...


Why the magnitude of a vector is always positive?

Magnitude is the absolute value which is always positive.--Edit: Magnitude is a scalar quantity thus regardless of the direction of the vector (which determines is positivity or negativity) the magnitude would be positive.Example: you take two steps forwards; the magnitude is two steps, regardless of it being forward or backwards (positive or negative)


What is scaler quantities and vector quantities?

scalar quantity has only magnitude whereas vector quantity has magnitude as well as direction
