A) \[{{y}^{2}}=8x\]
B) \[{{y}^{2}}=-8x\]
C) \[{{y}^{2}}=\sqrt{8}x\]
D) \[{{x}^{2}}=8y\]
E) \[{{x}^{2}}=-8y\]
Correct Answer: E
Solution :
\[\because \]Directrix of parabola is\[y=2.\] \[\therefore \] \[a=-2\] \[\therefore \]Required equation of parabola is \[{{x}^{2}}=-4.2.y\] \[\Rightarrow \] \[{{x}^{2}}=-8y\]
