The point dividing the join of \((3,-2,1)\) and \((-2,3,11)\) in the ratio \(2: 3\) is
- A \((1,1,4)\)
- B \((1,0,5)\)
- C \((2,3,5)\)
- D \((0,6,-1)\)
Answer & Solution
Correct Answer
(B) \((1,0,5)\)
Step-by-step Solution
Detailed explanation
Let require point is \(P\), then by section formula the coordinate of point \(P\) are \(\Rightarrow P\left(\frac{m x_2+n x_1}{m+n}, \frac{m y_2+n y_1}{m+n}, \frac{m z_2+n z_1}{m+n}\right)\) \(\Rightarrow \quad P\left(\frac{-4+9}{2+3}, \frac{6-6}{2+3}, \frac{22+3}{2+3}\right)\)…
