दो बिन्दुओं के स्थिति सदिश क्रमशः \(P(2\hat{i}+\hat{j}+3\hat{k})\) तथा \(Q(-4\hat{i}+2\hat{j}+\hat{k})\) है। Q से गुजरने वाले तथा PQ के लम्बवत् समतल का समीकरण होगा।

(a) \(\overrightarrow{r}\).\((6\hat{i}+3\hat{j}+2\hat{k})=28\)

(b) \(\overrightarrow{r}\).\((6\hat{i}+3\hat{j}+2\hat{k})=32\)

(c) \(\overrightarrow{r}\).\((6\hat{i}+3\hat{j}+2\hat{k})=28 = 0\)

(d) \(\overrightarrow{r}.(6\hat{i}+3\hat{j}+2\hat{k})+32 = 0\)
