4. What is position vector r? What is its magnitude?
Answers
Answer:
In geometry, a position or position vector, also known as location vector or radius vector, is a Euclidean vector that represents the position of a point P in space in relation to an arbitrary reference origin O. Usually denoted x, r, or s, it corresponds to the straight line segment from O to P.
Explanation:
The magnitude of the position vector is equal to the coordinate value r of the point the position vector is pointing to! A: That's right! The magnitude of a directed distance vector is equal to the distance between the two points—in this case the distance between the specified point and the origin!
Answer:
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.
