Q. |
## Which of the following is incorrect about Parabola? |

A. | eccentricity is less than 1 |

B. | mathematical equation is x2 = 4ay |

C. | length of latus rectum is 4a |

D. | the distance from the focus to a vertex is equal to the perpendicular distance from a vertex to the directrix |

Answer» A. eccentricity is less than 1 | |

Explanation: the eccentricity is equal to one. that is the ratio of a perpendicular distance from point on curve to directrix is equal to distance from point to focus. the eccentricity is less than 1 for an ellipse, greater than one for hyperbola, zero for a circle, one for a parabola. |
