If the circle C 1 : x² + y² = 16 intersects another circle C 2 of radius 5 in such a manner that the common chord is of maximum length and has a slope equal to 3/4, then the co − ordinates of the centre of C 2 are:
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
CHECK THE SOLUTION.
(b,d) 
slope of C 1 C 2 is tan α = – 
By using parametric coordinates C 2 (± 3 cos α , ± 3 sin α )
C 2 (± 3 (–3/5) , ± 3 (4/5)
C 2 (± 9/5 , 12/5)
