Q. |
## If the distance from a fixed straight line is equal to the distance from a fixed point then what is the value of eccentricity? |

A. | unity |

B. | greater than one |

C. | infinity |

D. | zero |

Answer» A. unity | |

Explanation: the fixed straight line is called as directrix and the fixed point is called as a focus. eccentricity is defined as the ratio of the distance from the focus to the distance from the directrix and it is denoted by e. |
