A) 2
B) 4
C) 6
D) 8
E) none of these
Correct Answer: B
Solution :
\[\because \]\[x+y+1=0\]touches the parabola\[{{y}^{2}}=\lambda x,\]then \[-1=\frac{\lambda /4}{-1}\] \[\left[ \because C=\frac{a}{m} \right]\] \[\Rightarrow \] \[\frac{\lambda }{4}=1\] \[\Rightarrow \] \[\lambda =4\]You need to login to perform this action.
