Find the vector of magnitude 11 units in the direction opposite to pqwhere p(1 3 2) and q(-1 0 8) |
|
Answer» <P>The vector with INITIAL POINT P(1,3,2) And TERMINAL point Q(-1,0,8) is given by PQ = (-1-1)i + (0-3)j + (8-2)k PQ = - 2i - 3j + 6K QP = -PQ = - 1(- 2i - 3j + 6k) QP vector = 2i +3j - 6k IQPI = IQPI = Therefore unit vector in direction of QP vector is given by QP unit vector = QP vector/IQPI QP unit vector = (2i +3j - 6k)/7 QP unit vector = (2/7) i + (3/7) j - (6/7) k Hope my answer and picture attached will satisfy you. |
