There are two vectors A = 6 i + 9 j - k and B = 2 i + 3 j - p k which have the same direction. The value of 'p' is

Options

  1. A3
  2. B1 3
  3. C2 3
  4. D- 1 3

Correct answer

B. 1 3

Step-by-step solution

Since the vectors A and B have the same direction, they are parallel. Their corresponding components must be proportional. A_x B_x = A_y B_y = A_z B_z Substituting the given values: 6 2 = 9 3 = -1 -p 3 = 3 = 1 p p = 1 3 Answer: 1 3
