Let the radius of earth be 6400km if it shrink by 2% then how it will increase

F=ma=GMm/r²
on the surface of the earth
g=a=GM/r², M is the mass of the earth, which is a constant in this case
So if radius shrinks.
Then, Acceleration due to gravity increases as radius is inversely proportional to Acceleration due to gravity.
