lies on C, then 
is equal to
Text Solution
Verified by ExpertsThe correct answer is:
118
(118)
any point P 
is
this is normal is also thenormal of the circle passing through the point 
So,
or 
(Not possible)
and 
so point P 
So the largest radius of circle
So the equation of circle 
Passing it through 
Then
