Find the vector product A x B (expressed in unit vectors) of the two vectors given in Exercise 1.38. What is the magnitude of the vector product? Given two vectors A = 4.00 i + 7.00j and B = 5.00 i − 2.00

(II) Let us show that Eq. 11–3c is equivalent to the definition of cross product, Eq. 11–3a and the sentence below it including the right-hand rule and Fig. 11–7. We do this in three parts.

(iii) Finally, choose a coordinate system so that A→ = Aₓ î and B→ = Bₓ î + Bᵧ ĵ and show that follows the right-hand rule C→ =A→ x B→ .
