If the angle between the line x+1 1 = y-1 2 = z-2 2 and the plane 2 x-y+ z+4= 0 is such that = 1 3 the value of is

Options

  1. A5 3
  2. B-3 5
  3. C3 4
  4. D-4 3

Correct answer

A. 5 3

Step-by-step solution

Angle between line and normal to plane is ( 2 - )= 2-2+2 3 5+ where is angle between line & plane = 2 3 5+ = 1 3 = 5 3 .
