Question

If radius of earth shrink by 1 percent and it's mass remain same the acceleration due to gravity on surface of earth would be

Answer 1

Earth's sun)

and the radius to over 1 AU. According to a 2008 model, Earth's orbit is shrinking due to tidal forces (and, eventually, drag from the lower chromosphere)

Answer 2

The general relation between acceleration and radius is:

a = GM/r^2

Generally in earth: g=GM/r^2   ( r is the radius of earth and M is the mass of earth )

In your case :  g(new)=GM/(0.99r)^2

g(new)= g/ (0.9)^2
