Question

The centre of sphere passes through four points (0, 0, 0), (0, 2, 0), (1, 0, 0) and (0, 0, 4) is

• A.
  
• B.
  
• C.
  
• D.
  

Answer 1

The correct option is A

Let the equation of sphere
$x^2+y^2+z^2+2ux+2vy+2wz+d=0$
$\because$ It passes through origin (0,0,0),
$\therefore$ d =0
Also, it passes through (0,2,0)
