Consider the following statements : 1. The direction ratios of y -axis can be 0,4,0 2. The direction ratios of a line perpendicular to z -axis can be 5,6,0 Which of the statements given above is/are correct?

Options

  1. A1 only
  2. B2 only
  3. CBoth 1 and 2
  4. DNeither 1 nor 2

Correct answer

C. Both 1 and 2

Step-by-step solution

The direction cosines of y -axis are 0,1,0 The direction ratio of y -axis are in the form 0, a, 0 , a R So, statement 1 is correct. We have direction ratio of a line perpendicular to Z -axis are in the form a, b, 0 So, statement 2 is correct.
