Question

what is the value of acceleration due to gravity on the surface of earth ​

Answer 1

Answer:

9.8 m/s2

In the first equation above, g is referred to as the acceleration of gravity. Its value is 9.8 m/s2 on Earth. That is to say, the acceleration of gravity on the surface of the earth at sea level is 9.8 m/s2.

Answer 2

Answer:

9.8 m/s2

Explanation:

by Newton's second law,

F=ma

here a replaces by g

since force involved is gravity,

F=GMm/r^2

then

GMm/r^2=mg

g=GM/r^2

g=6.673×10^-11(5.96×10^24)/(6.4×10^6)^2m/s^2

g=9.8m/s2
