A) \[2<r<8\]
B) \[r=2\]
C) \[r<2\]
D) \[r>2\]
Correct Answer: A
Solution :
When two circles intersect each other, then Difference between their radii<Distance between centers \[\Rightarrow r-3<5\Rightarrow r=8\] .....(i) Sum of their radii > Distance between centres .....(ii) \[\Rightarrow \] \[r+3>5\Rightarrow r>2\] Hence by (i) and (ii), \[2<r<8\]You need to login to perform this action.
