Answer 1

hi

If however a vector is multiplied by a negative number (for example -2, -3 ,-5, -60 unit etc.) or a scalar not only its magnitude is changed but its direction also reversed. The product of a vector by a scalar quantity (m) follows the following rules: (m) = (m) which is called commutative law of multiplication.
