A) \[(5,10)\]
B) \[(5,5)\]
C) \[(-5,10)\]
D) \[(-5,-10)\]
Correct Answer: A
Solution :
Let the pole be\[({{x}_{1}},{{y}_{1}}),\]then polar is \[x{{x}_{1}}+y{{y}_{1}}=5\] ...(i) But given polar is \[x+2y=1\] ...(ii) On comparing Eqs.(i) and (ii), \[\frac{{{x}_{1}}}{1}=\frac{{{y}_{1}}}{2}=\frac{5}{1}\] \[\Rightarrow \] \[{{x}_{1}}=5,{{y}_{1}}=10\] Hence, pole is (5,10)You need to login to perform this action.
