Question

Fixed vectors are those vectors whose ________ position is fixed
A. Final
B. Initial
C. Can be both
D. None of the above

Answer 1

Hint: In physics a vector is a mathematical representation of a physical quantity that has some magnitude and a specific direction. A vector is formed by joining two points in a specific direction. Examples of vector quantities are force, acceleration and velocity.

Complete answer:
Let us first understand what a vector is. In mathematics, a vector is a line segment with a specific direction, like an arrow. A vector is formed by joining two points in a specific direction.In physics, a vector is used to represent various physical quantities. The physical quantities that can be represented by vectors are called vector quantities. Vector quantities are those quantities that have some magnitude and a specific direction.

Some of the different types of vector are null vector, position vector and fixed vector. Null vector is a vector that has no magnitude or we can also say that a null vector has zero magnitude. Null vector is also called a zero vector.Position vector is a vector that is formed by joining a point and the origin. A fixed vector is a vector with its initial position (initial point) fixed.

Hence, the correct option is A.

Note:The position vector tells us about the position of a point in the Cartesian coordinate system with respect to the origin (a reference point). It is always formed by joining the origin and the point and the direction of the vector is always from origin towards the point (away from the origin).
