just divide the vector by its lenght. Square root of 4+9=square root of 13, so divide by that 2/Sqrt(13) -3/Sqrt(13)

Can a vector be represented in terms of unit vector?

Yes, a vector can be represented in terms of a unit vector which is in the same direction as the vector. it will be the unit vector in the direction of the vector times the magnitude of the vector.


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.


Define the unit vector?

The unit vector is a vector whose magnitude is 1.


Can you add three unit vector to get a unit vector?

Yes.


When was Vector Unit created?

Vector Unit was created in 2007.


Why A unit vector is a vector but a vector is not a unit vector?

A unit vector is one which has a magnitude of 1 and is often indicated by putting a hat (or circumflex) on top of the vector symbol, for example: Unit Vector = â, â = 1.The quantity â is read as "a hat" or "a unit".


What is unit vector in physics?

a vector having unit magnitude and have a certain direction.


Can a unit vector have any components with magnitude greater than unity?

No, by definiton, a unit vector is a vector with a magnitude equal to unity.


If a vector quantity is divided by its magnitude the vector obtained is called?

A unit vector.


If all the components of a vector are equal to 1 then that vector is a unit vector?

False.


What is the resultant of a 3 unit vector and 4 unit vector at right angles to each other?

A vector of magnitude 5 units, in the direction 0.6435 radians from the 3-vector (towards the 4-vector)


What is a unit vector in mathematics?

A vector of magnitude 1.


What is the minimum resultant possible when adding a 3 unit vector to an 8 unit vector?

11


What are unit vectors?

a unit vector is a vector which has exact same direction and has its length or magnitude equal to one


When vector is divided by its own magnitude you find its?

We get the Unit Vector


What is the resultant of a 3-unit vector and 4-unit vector at right angles to each other?

The multiplicative resultant is a three unit vector composed of a vector parallel to the 3 unit vector and a vector parallel to the product of the 3 unit and 4 unit vectors. R = (w4 + v4)(0 +v3) = (w40 - v4.v3) + (w4v3 + 0v4 + v4xv3) R = (0 - 0) + w4v3 + v4xv3 as v4.v3 =0 ( right angles or perpendicular)


Prove that the unit vector is dimenssionless?

The unit vector is the ratio of the vector and its magnitude, thus : R/r = (Ix + Jy + Kz)/r where r= Sqroot(x^2 + y^2 + z^2). Units of the vector and the magnitude are the same thus divide out and the unit vector is dimensionless.


How can you find a unit vector in the same direction as the given vector?

Divide the vector by it's length (magnitude).


Why unit vector has magnitude one?

That's what "unit" means.

A scalar quantity multiplied by a unit vector is a scalar quantity?

Scalars are quantities that are described by a magnitude alone. A scalar quantity multiplied by a unit vector is not a scalar quantity but a vector quantity.


Dot product of unit vectors of cartesian and cylindrical coordinate system?

Unit vectors are perpendicular. Their dot product is zero. That means that no unit vector has any component that is parallel to another unit vector.


What is the difference between unit vectors and column vectors?

a unit vector is any vector with length or absolute value 1. A column vector is any vector written in a column of since we say an mxn matrix is m rows and n columns, a column vector is mx1 matrix.


What is meant by rectangular unit vector?

A unit vector has a length (magnitude) equal to 1 (one unit). A rectangular vector is a coordinate vector specified by components that define a rectangle (or rectangular prism in three dimensions, and similar shapes in greater dimensions). The starting point and terminal point of the vector lie at opposite ends of the rectangle (or prism, etc.).
