Question

define the terms 1) co-initial vector 2) negative of vector.​

Answer 1

Answer:

. Co-initial Vectors: Any given two vectors are called as co-initial vectors if both the given vectors have the same initial point. Negative vector. A negative vector is a vector which points in the direction opposite to the reference positive direction.

Answer 2

Question :-

Define the terms :-

• Co-initial vector

• Negative of vector.

Answer :-

First we can know abour vector,

• A vector is an object that has both a magnitude and a direction. Geometrically, we can picture a vector as a directed line segment, whose length is the magnitude of the vector and with an arrow indicating the direction.

For eg :-

• Examples of vectors are those that represent force and velocity.

Now we can goes to the question,

What is Co-initial vector ?

• Any two vectors are called co-initial vectors if both have same initial point i.e. they originate from the same point.

For eg :-

• OA and OB have initial point O. So, they are co-initial vectors.

What is Negative of vector ?

• A negative vector is a vector which points in the direction opposite to the reference positive direction. A negative vector is a vector that has the opposite direction to the reference positive direction. Like scalars, vectors can also be added and subtracted.

For eg :-

• If in a particular situation, we define the upward direction as the reference positive direction, then a force →F1=30 N downwards would be a negative vector and could also be written as →F1=−30 N.
