Q. |
## is a curve generated by a point on the circumference of a circle which rolls without slipping on a straight line. |

A. | trochoid |

B. | epicycloid |

C. | cycloid |

D. | evolute |

Answer» C. cycloid | |

Explanation: trochoid is curve generated by a point fixed to a circle, within or outside its circumference, as the circle rolls along a straight line. cycloid is a curve generated by a point on the circumference of a circle which rolls along a straight line. ‘epi’ represents the directing path is a circle. |
