The variation of -apos-g-apos- with altitude is- g-x2032-g-1-x2212-2hR-The variation of -apos-g-apos- with depth is- g-x2032-g-1-x2212-dR-So- from the above equations we can deduce that if a person goes deep into a mine or to a height above the Earth-apos-s surface- the gravitational field decreases at different rates-

The variation of 'g' with altitude is: g′=g(1−2hR)The variation of 'g' with depth is: g′=g(1−dR)So, from the above equations we can deduce that if a person goes deep into a mine or to a height above the Earth's surface, the gravitational field decreases at different rates.
