The circle x^2+y^2+2lambdax=0,lambda in R , touches the parabola y^2=4x externally. Then, (a) lambda>0 (b) lambda 1 (d) none of these

The circle x^2+y^2+2lambdax=0,lambda in R , touches the parabola y^2=4x externally. Then, (a) lambda>0 (b) lambda 1 (d) none of these

The circle x^(2)+y^(2)+2 lambda x=0,lambda in R, touches the parabola y^(2)=4x externally.Then,lambda>0 (b) lambda 1(d) none of these

If the circle x^2 + y^2 + lambdax = 0, lambda epsilon R touches the parabola y^2 = 16x internally, then (A) lambda lt0 (B) lambdagt2 (C) lambdagt0 (D) none of these

The circle x^(2)+y^(2)+4 lambda x=0 which lambda in R touches the parabola y^(2)=8x The value of lambda is given by

If 2 x+y+lambda=0 is a normal to the parabola y^(2)=8 x, then lambda=

If x+y+1=0 touches the parabola y^(2)=lambda x then lambda=

If 2x+y+lambda=0 is a normal to the parabola y^2=-8x , then lambda is

If x+y+1 = 0 touches the parabola y^(2) = lambda x , then lambda is equal to
