The ratio in which the Y Z - plane divides the line joining ( 2 , 4 , 5 ) and ( 3 , 5 , - 4 ) is

Options

  1. A2 : 3  internally 
  2. B3 : 2  internally 
  3. C3 : 2  externally 
  4. D2 : 3  externally 

Correct answer

D. 2 : 3  externally 

Step-by-step solution

Given points ( 2 , 4 , 5 ) and ( 3 , 5 , - 4 ) The ratio divided by Y Z plane in which it divides x 1 , y 1 , z 1   &   x 2 , y 2 , z 2 is = - x 1 x 2 =   - 2 3 As the ratio is negative it will divide in 2   :   3 externally.
