Question

derive an an expression variation of acceleration due to gravity with the their hight​

Answer 1

${\tt{\red{\underline{\underline{\huge{Answer:}}}}}}$

For an object placed at a height h, the acceleration due to gravity is less as compared to that placed on the surface. As depth increases, the value of acceleration due to gravity (g) falls.

The value of g is more at equator and less at poles.

The value of g is more at equator and less at poles.Formula: g = GM/r²

Values of g in SI: 9.806 ms-²

Values of g in CGS: 980 cm s-²

Dimensional Formula: M0L1T-²
