1. Consider the two vectors P and Q. The definition of P is P = i × (i × j). The
definition of Q is Q = (i × i) × j .
a. The magnitude of P is equal to the magnitude of Q.
b. The magnitude of P is greater than the magnitude of Q.
c. The magnitude of P is less than the magnitude of Q.
Is the answer A

P
(i x j) = k
i x k = j
Q
i x i = 0
0 x j = 0
soP > Q
