Formula of unit vector

WebEquation 2.2 is a scalar equation because the magnitudes of vectors are scalar quantities (and positive numbers). If the scalar α is negative in the vector equation Equation 2.1, then the magnitude B → of the new vector is still given by Equation 2.2, but the direction of the new vector B → is antiparallel to the direction of A →.
