Mathematics Question on Three Dimensional Geometry

XY - plane divides the line joining the points A (2, 3, - 5) and B (-1, -2, -3) in the ratio

A

5 : 3 internally

B

2 : 1 internally

C

5 : 3 externally

D

3 : 2 externally

Answer

5 : 3 externally

Explanation

Solution

Equation of xy-plane is z = 0
Ratio in which xy-plane
divides=−(−5)−3=−53-\frac{\left(-5\right)}{-3}=-\frac{5}{3}
