The ratio in which the plane r . ( i -2 j +3 k )=17 divides the line joining the points -2 i +4 j +7 k and 3 i -5 j +8 k

Options

  1. A10:3
  2. B3: 10
  3. C5: 3
  4. D4: 5

Correct answer

B. 3: 10

Step-by-step solution

Let the required ratio be : 1 then the point of division lies on the plane. aligned & 3 -2 +1 -2 x -5 +4 +1 +3 8 +7 +1 =17 & = 3 10 aligned The required ratio is 3: 10
