TS EAMCET · Maths · Three Dimensional Geometry
The position vectors of the points and are respectively and The ratio in which the point having position vector divides the line segment joining and is
- A
- B
- C
- D
Answer & Solution
Correct Answer
(D)
Step-by-step Solution
Detailed explanation
x-coordinate of A =3λ+1-2λ+1=-92 ⇒23λ-2=λ+1-9 ⇒15λ=-5 λ=-13 So, A is dividing PQ externally in ratio 1:3.
