Answer 1

Answer:

(1) The vector possessing magnitude equal to one and same direction as that of the given vector is known as a unit vector. It is denoted as A^. (2) Zero vector or null vector is the vector whose magnitude is zero and has no any sense of direction.

The vector possessing magnitude equal to one and same direction as that of the given vector is known as a unit vector. It is denoted as A^. (2) Zero vector or null vector is the vector whose magnitude is zero and has no any sense of direction.Explanation:

3. Position vector, straight line having one end fixed to a body and the other end attached to a moving point and used to describe the position of the point relative to the body. As the point moves, the position vector will change in length or in direction or in both length and direction.
