Acceleration due to gravity.
g1=‌

GM

R12

As, M remain constant and R becomes
Therefore, the new gravitational acceleration becomes,
Change in the gravitational acceleration,
g2−g1=1.02g1−g1=0.02g1
Hence, the percentage increase is
‌

g2−g1

g1

×100=0.02×100=2%
So, if the radius of earth shrinks by 1%, the value of g would increase by 2%.
