Obtain a unit vector perpendicular to the two vectors given in Exercise 1.41.

Answer: The unit vector perpendicular to both the given two vectors I.e A= -2i + 3j + 4 k B= 3i + 1j - 3k Unit vector perpendicular to the given vector can be given as a x b = - 14i + 6j - 11k | a x b| = ( 14) + (6) + ( 11) = 353 Now the unit vector of the two vectors is given by a x b = - 14i + 6j - 11k / 353 |a x b|
