Question

1. How does value of gravity vary at equator and at poles?
2. The earth's gravitational force causes an acceleration of 5 metre per second square on 1 kg mass somewhere in space. How much will the acceleration of 3kg mass will be at the same place?

Answer 1

Answer:

1) Ans= , the equatorial bulge and the effects of the surface centrifugal force due to rotation mean that sea-level gravity increases from about 9.780 m/s2 at the Equator to about 9.832 m/s2 at the poles, so an object will weigh approximately 0.5% more at the poles than at the Equator.

2) Ans= This answer is in the above picture!
