Question

If the earth does not rotate on its axis, the change in the weight of a body at the equator would be about (Take radius of earth-6400 km)

• A. 0.003%v larger
• B. 0.3% longer
• C. 0.3% smaller
• D. 0.003% smaller

Answer 1

The correct option is B 0.3% longer

Not much of an increase - max. only about 0.3% on the equator. The surface of the Earth, in a rotating frame, is rotating with a period of about 24 hours. The velocity of 465.10 meters per second is directed eastwards and is faster than the speed of sound. The centrifugal acceleration on the equator
