A) \[\left( \frac{{{a}^{2}}l}{n},\frac{{{a}^{2}}m}{n} \right)\]
B) \[\left( \frac{-{{a}^{2}}l}{n},\frac{-{{a}^{2}}m}{n} \right)\]
C) \[\left( \frac{{{a}^{2}}n}{l},\frac{{{a}^{2}}n}{m} \right)\]
D) None of these
Correct Answer: B
Solution :
Suppose point be (h, k). Equation of common chord of contact is \[hx+ky-{{a}^{2}}=0\equiv lx+my+n=0\] or \[\frac{h}{l}=\frac{k}{m}=\frac{-{{a}^{2}}}{n}\] or \[h=\frac{-{{a}^{2}}l}{n}\], \[k=\frac{-{{a}^{2}}m}{n}\].You need to login to perform this action.
