\( X Y \) - plane divides the line joining the points \( A(2,3,-5) \) and \( B(-1,-2,-3) \) in the ratio
- A \( 3: 2 \) externally
- B \( 5: 3 \) externally
- C \( 2 \) : \( 1 \) internally
- D \( 5: 3 \) internal
Answer & Solution
Correct Answer
(B) \( 5: 3 \) externally
Step-by-step Solution
Detailed explanation
(B)
Equation of xy-plane is \( z=0 \)
Ratio in which xy-plane
divides \( =-\frac{(-5)}{-3}=-\frac{5}{3} \)
