(C) The acceleration due to gravity $g$ on the surface of the earth is given by the formula $g = \frac{GM}{R^2}$,where $G$ is the gravitational constant,$M$ is the mass of the earth,and $R$ is its radius.Since the mass $M$ remains constant,we have $g \propto \frac{1}{R^2}$.Taking the logarithmic differentiation,we get $\frac{\Delta g}{g} = -2 \frac{\Delta R}{R}$.Given that the radius shrinks by $1\%$,we have $\frac{\Delta R}{R} = -0.01$.Substituting this value,$\frac{\Delta g}{g} = -2 	imes (-0.01) = 0.02$.Therefore,the acceleration due to gravity increases by $2\%$.
