Question

explain the value of g i.e accelerate due to gravity changes as we move towards the center of earth​

Answer 1

$\huge{\mathfrak{\underline{\orange{Answer}}}}$

Under the action of gravitational force, the body begins to accelerate toward the earth's centre which is at a distance 'r' from the test mass. ... Its value near the surface of the earth is 9.8 ms-2. Therefore, the acceleration due to gravity (g) is given by = GM/r2.

Values of g in SI: 9.806 ms-2

Values of g in CGS: 980 cm s-2

Formula: g = GM/r2

Dimensional Formula: M0L1T-2
