Find the scalar components of a unit vector which is perpendicular to each of the vector  and .

Answer:

Let  and  is a unit vector perpendicular to both                                          ? (1)          Also                   and             3x ? y + 2z = 0        x + 2y ? z = 0       and 3x ? y + 2z = 0                         Putting the values of x, y and z in (1)       (3k)2 + (?5k)2 + (?7k)2 = 1                    scalar components are             or
