  1. A x2+y2+x+y=0
  2. B x2+y2-x-y=0
  3. C x2+y2-3x+y=0
  4. D x2+y2+3x-y=0
Verified Solution

Answer & Solution

Correct Answer

(B) x2+y2-x-y=0

Step-by-step Solution

Detailed explanation

We have equation of line y = x and equation of circle x2+y2-2x=0

Now, intersecting points of given line and circle
x2+x2-2x=0
2x2-2x=0
2xx-1=0
x=0,1
When x = 0 then y =0 when x =1 then y = 1
Coordinates of end points of diameter AB are (0, 0) and (1, 1)
Required equation of circle with diameter AB
x-0x-1+y-0y-1=0
x2-2+y2-y=0
x2+y2-x-y=0
