Question

3)Write expression for the acceleration due to gravity at surface of

earth.​

Answer 1

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.

Answer 2

Answer:

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.

Dimensional Formula: M0L1T-2

Formula: g = GM/r2

Values of g in SI: 9.806 ms-2

Values of g in CGS: 980 cm s-2
