BPSC – Combined Competitive Examination · प्रश्न 116

If the Earth's speed of rotation increased, the weight of a body at the equator would:

  1. decrease
  2. not change
  3. double
  4. increase
  5. None of the above / More than one of the above
उत्तर दाखवा आणि स्पष्टीकरण

उत्तर: (A) decrease

स्पष्टीकरण

At the equator effective g = g − ω²R, so faster rotation lowers weight (no change at the poles).

  • (A) बरोबर

    Correct: greater centrifugal effect reduces apparent weight (g' = g − ω²R).

  • (B) चूक

    Wrong: it does change at the equator.

  • (C) चूक

    Wrong: incorrect.

  • (D) चूक

    Wrong: it decreases.

  • (E) चूक

    Wrong: only one of the options A–D is correct.
