The equation of the circle whose radius is 5 and which touches the circle 
externally at the point (5, 5), is
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
B
Let the centre of the required circle be 
and the centre of given circle is (1, 2). Since radii of both circles are same, therefore, point of contact (5, 5) is the mid point of the line joining the centres of both circles. Hence 
and 
. Hence the required equation is 
.
