WebTo multiply a vector by a scalar, multiply each component by the scalar. If →u = u1, u2 has a magnitude →u and direction d , then n→u = n u1, u2 = nu1, nu2 where n is a positive real number, the magnitude is n→u , and its direction is d . Note that if n is negative, then the direction of nu is the opposite of d . Example :
