Question

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

Answer 1

Hint:In physics, a vector is a quantity of both magnitude and direction. It's usually represented by an arrow of the same direction as the quantity and a length equal to the magnitude of the quantity. A vector does not have location, even though it has magnitude and direction. A vector is not altered if it is moved parallel to itself as long as its length is not changed.

Complete answer:
In physics, a vector is a quantity of both magnitude and direction. It's usually represented by an arrow of the same direction as the quantity and a length equal to the magnitude of the quantity. A vector does not have location, even though it has magnitude and direction. A vector is not altered if it is moved parallel to itself as long as its length is not changed.

Fixed Vector: A vector with a single point of application that can be slid down its line of operation to analyse the external impact it has on a body like a sliding vector (How it affects the body as a whole).

Consider the following scenario: The front-facing submarine is affected by two vectors: an upthrust buoyancy vector and a weight vector. These two are "slid" through their lines of operation to see what impact they have on the submarine from the outside.

A fixed vector cannot be used to investigate internal effects. The original point or tail of a set vector is still the same. Localised vector is another name for it. The centre of the coordinate axes, for example, is set at the initial point of a direction vector.

Hence, option A is correct.

Note:The addition and subtraction of vector quantities does not follow the simple arithmetic rules. A special set of rules are followed for the addition and subtraction of vectors. The addition of scalar quantities follows the simple rules of the algebra.
