Question

examples of null vector, free vector, position vector and unit vector

Answer 1

null next is 0 zero direction position vectors are taken frm origin and unit vector is very important for eg. 10 Newton upon 10 Newton it will get cancelled and there is only unit left

Answer 2

Answer:

A vector having zero magnitude (arbitrary direction) is called the null (zero) vector. The zero vector is unique. For eg:- A point have no magnitude and an arbitrary direction. Unit vector is a vector of unit length.
