The direction cosines of a line are ( -9 11 , 6 11 , -2 11 ) respectively. Then its direction ratios are

Options

  1. A( 9,6,-2 )
  2. B( -9,-6,2 )
  3. C( -9,6,-2 )
  4. D( 9,-6,-2 )

Correct answer

C. ( -9,6,-2 )

Step-by-step solution

Direction cosines of a line are given as ( - 9 11 , 6 11 ,- 2 11 ) respectively, so the direction ratios are (-9,6,-2 ) respectively. Hence, option (c) is correct.
