Question

Why we sometime take length as a vector quantity while it is a scalar ( as we take length as a vector quantity in F = I (L×B)

Answer 1

Answer:

A vector quantity is any quantity that has magnitude and direction, such as displacement or velocity. ... The length of the vector is its magnitude, which is a positive scalar. On a plane, the direction of a vector is given by the angle the vector makes with a reference direction, often an angle with the horizontal.
