Given A = 2 i - 2 j + 8 k and B = 2 i - m j + 8 k , if A and B have the same direction, the value of m is

Options

  1. A1
  2. B2
  3. C3
  4. D4

Correct answer

B. 2

Step-by-step solution

For two vectors A and B to have the same direction, their corresponding components must be proportional with a positive ratio. A_x B_x = A_y B_y = A_z B_z Substituting the given values: 2 2 = -2 -m = 8 8 1 = 2 m = 1 m = 2 Answer: 2
