A) \[5x-10y+2=0\]
B) \[6x-y-20=0\]
C) \[10x-y-10=0\]
D) \[x-10y-2=0\]
Correct Answer: B
Solution :
The polar of the point \[\left( 5,\ -\frac{1}{2} \right)\] is \[x{{x}_{1}}+y{{y}_{1}}+g(x+{{x}_{1}})+f(y+{{y}_{1}})+c=0\] \[\Rightarrow 5x-\frac{1}{2}y-2(x+5)+0+0=0\] \[\Rightarrow 3x-\frac{y}{2}-10=0\Rightarrow 6x-y-20=0\].You need to login to perform this action.
