1. The problem statement, all variables and given/known data This problem actually has 2 parts. For vectors a= (2,p,8) and b= (q,4,12), determine the values of p and q so that the vectors are a)perpendicular b) collinear textbook answer: a) p= 1 and q= -50 (answers may vary) b) p= 8/3 and q=3 2. Relevant equations a*b = 0 a*b = a1b1 + a2b2 + a3b3 3. The attempt at a solution So for the first part, I used a*b = 0 and I don't know how to do the second part a*b = 0 (2,p,8)*(q,4,12) = 0 2q + 4p + 96 =0 I tried isolating p and q and substituting them but I end up with 0.
