Question

What is meant by acceleration die to gravity?derive an expression for acceleration due to gravity in terms of mass M of Earth and its radius R

Answer 1

acceleration due to gravity means the acceleration gained by the body due to gravitational force of the earth . I hope My answer will help u ..

Answer 2

It's not acceleration die to gravity its acceleration due to gravity...
An object gains acceleration due to gravitational force then it is called acceleration due to gravity...

DERIVATION:
We know that,,,,
F directly propotional to Mm
F inversly propotional to R^2
G is the Universal gravitaional constant
F=mg
F=GMm/R^2
mg=GMm/R^2
g=GM/R^2
Here;
F=Force
M/m=masses
g=acceleration due to gravity
R=radius
