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
ಉತ್ತರ ತೋರಿಸು ಮತ್ತು ವಿವರಣೆ

ಉತ್ತರ: (A) decrease

ವಿವರಣೆ

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

  • (A) ಸರಿ

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

  • (B) ತಪ್ಪು

    Wrong: it does change at the equator.

  • (C) ತಪ್ಪು

    Wrong: incorrect.

  • (D) ತಪ್ಪು

    Wrong: it decreases.

  • (E) ತಪ್ಪು

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