Question

Cartesian Vectors (Write True or False)

1. Geometric vectors have both magnitude and direction but Cartesian vectors have only magnitude.

2. Unit vectors have a magnitude of one but no direction

3. The product of a vector and scalar is a vector.

4. There is no such thing as a zero vector.

5. A Cartesian vector uses coordinates to describe it fully

6. .The dot product of two vectors is a vector.

Answer 1

1.false

Explanation :Geometric or spatial vector have both magnitude and direction, and Cartesian vector have both magnitude and direction.

2.false

Explanation : unit vector has magnitude one and direction as same as vector direction

3.true

Explanation : the product of vector and scalar is vector.

4.false

Explanation : zero vector is vector with length has 0.

5.true

Explanation : yes, with help of coordinates we can describe Cartesian vector

6.false

Explanation :the dot product of two vectors is scalar
