Locus of a point at which the circles x 2 + y 2 –2x –2y –7 = 0 and x 2 + y 2 + 8x + 6y = 0 subtend equal angles, is -
Text Solution
Verified by ExpertsThe correct answer is:
C
Two circles cut each other, also locus is obtained by 2tan –1 
= 2 tan –1 
which is 16x 2 + 16y 2 – 122 x – 104y – 175 = 0 whose centre lies outside smaller circle .
