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 a 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

The correct option is B Decrease a the equator but remain unchanged at the poles

Faster rotation of the earth results in decreased weight apparently. This decrease is not felt at the poles as angle of latitude is ${90}^{\circ }$ there.
