The distance between the lines x 2 = y -1 = z 2 and x-1 2 = y-1 -1 = z-2 2 is

Options

  1. A3 units
  2. B2 units
  3. C1 unit
  4. D2 units

Correct answer

B. 2 units

Step-by-step solution

Distance between the liens = | array ccc i & j & k 1-0 & 1-0 & 1-0 2 & -1 & 2 array | 2^2+(-1)^2+2^2 = |3 i -3 k | 9 = 3^2+3^2 3 = 2
