BPSC – Combined Competitive Examination · প্রশ্ন 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
উত্তর দেখান ও ব্যাখ্যা

উত্তর: (A) decrease

ব্যাখ্যা

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

  • (A) সঠিক

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

  • (B) ভুল

    Wrong: it does change at the equator.

  • (C) ভুল

    Wrong: incorrect.

  • (D) ভুল

    Wrong: it decreases.

  • (E) ভুল

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