B) \[{{x}^{2}}+{{y}^{2}}+x+y-1=0\]
C) \[{{x}^{2}}+{{y}^{2}}-2x-2y-1=0\]
D) None of these
Correct Answer: A
Solution :
The centre of given circle is (1, 1) and its radius is \[\sqrt{2}\]. From the figure, if \[M(h,\ k)\] be the middle point of chord AB subtending an angle \[\frac{2\pi }{3}\] at C, thenYou need to login to perform this action.
