A) \[\left( \frac{l}{n},\frac{m}{n} \right)\]
B) \[\left( -\frac{l}{n},-\frac{m}{n} \right)\]
C) \[\left( \frac{l}{n},-\frac{m}{n} \right)\]
D) \[\left( -\frac{l}{n},\frac{m}{n} \right)\]
Correct Answer: B
Solution :
Let pole be \[({{x}_{1}},{{y}_{1}})\] then polar will be \[x{{x}_{1}}+y{{y}_{1}}=1\] comparing with \[lx+my+n=0\] \[\Rightarrow {{x}_{1}}=-\frac{l}{n},\ {{y}_{1}}=-\frac{m}{n}\].
