Question

Q.26(a)How does gravity of earth varies if a body of mass m is at heighth and at depth

d.​

Answer 1

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.

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
