Question

The height to which the acceleration due to gravity becomes g9 (where g= acceleration due to gravity at surface of earth ) in terms of R, is

Answer 1

By Newton’s law of gravitation, g is inversely proportional to r2,

So, g‘ / g = [R / R+h ] 2

Put g’ = g/9;  h= 2R

Answer 2

Answer:

The answer is 2R
