Question 113

The points PPP, QQQ, R R\,R and S S\,S have position vectors p=2i−5j+4k\mathbf{p} = 2\mathbf{i} - 5\mathbf{j} + 4\mathbf{k}p=2i−5j+4k, q=10i+j−2k\mathbf{q} = 10\mathbf{i} + \mathbf{j} - 2\mathbf{k}q=10i+j−2k, r=−3i+7j+k\mathbf{r} = -3\mathbf{i} + 7\mathbf{j} + \mathbf{k}r=−3i+7j+k, s=9i+16j−8k\mathbf{s} = 9\mathbf{i} + 16\mathbf{j} - 8\mathbf{k}s=9i+16j−8k
