What are the co-ordinates of the foot of the perpendicular drawn from the point (3,5,4) on the plane z=0 ?

Options

  1. A(0,5,4)
  2. B(3,5,0)
  3. C(3,0,4)
  4. D(0,0,4)

Correct answer

B. (3,5,0)

Step-by-step solution

Plane z =0 is simply xy plane, so z quadrant value will be zero. So, options (2) is correct option.
