Question

If the earth were to rotate faster than its present speed, the weight of an object will

• A. increase at the equator but remain unchanged at the poles
• B. decrease at the equator but remain unchanged at the poles
• C. decrease at the poles but remain unchanged at the equator
• D. increase at the pole but remain unchanged at the equator

Answer 1

Answer: (B)

Faster rotation of the earth results in decreased weight apparently. This decrease is not felt at the poles as angle of latitude is $ \text{9}{{\text{0}}^{\text{o}}} $ there.
