\(X O Z\)-plane divides the join of \((2,3,1)\) and \((6,7,1)\) in the ratio:
- A \(3: 7\)
- B \(2: 7\)
- C \(-3: 7\)
- D \(-2: 7\)
Answer & Solution
Correct Answer
(C) \(-3: 7\)
Step-by-step Solution
Detailed explanation
Let \(X O Z\)-plane divides the joining the point \((2,3,1)\) and \((6,7,1)\) into \(m: n\), then the co-ordinate of \(X O Z\)-plane is \(\left(\frac{m x_2+n x_1}{m+n}, \frac{m y_2+n y_1}{m+n}, \frac{m z_2+n z_1}{m+n}\right)\)…
