A) \[ay=2b(x-b)\]
B) \[bx=2a(y-a)\]
C) \[by=2a(x-a)\]
D) \[ax=2b(y-b)\]
Correct Answer: C
Solution :
[c] Let the coordinates of the point T be (h, k). Chord of contact w.r.t. point T(h, k) is \[ky=2a(x+h).\]. It passes through \[(-a,b)\]. \[\Rightarrow \,\,\,bk=2a(-a+h)\] Therefore, the locus of T is by \[=2a\,(x-a).\]You need to login to perform this action.
