The component of vector A =a_x i +a_y j +a_z k along the direction of i - j is

Options

  1. Aa_x-a_y+a_z
  2. Ba_x-a_y
  3. C(a_x-a_y ) / 2
  4. D(a_x+a_y+a_z )

Correct answer

C. (a_x-a_y ) / 2

Step-by-step solution

Let B = i - j Then component of vector A along B aligned & = A B | B | & = (a_x i +a_y j +a_z k ) ( i - j ) | i - j | & = a_x-a_y 2 aligned
