Hi, I have a question and I hope anyone could answer it:

A particle is suspended from a string of length ‘R’. It is given a velocity u = 3 (sqrt{Rg}) . Match the following

Column I |
Column II |

(A) Velocity B | (p) 7 mg |

(B) Velocity at C | (q) (sqrt{5 gR}) |

(C) Tension at B | (r) (sqrt{7 gR}) |

(D) Tension at C | (s) 4mg |

A → r; B → q; C → p; D → s
