Question

find a unit vector in the dorection of the vector A=7i-20J​

Answer 1

Answer:

How to find the unit vector? To find a unit vector with the same direction as a given vector, we divide the vector by its magnitude. For example, consider a vector v = (1, 4) which has a magnitude of |v|. If we divide each component of vector v by |v| we will get the unit vector uv which is in the same direction as v.
