If all a sudden the radius of the earth increases, then

What will be the percentage increases or decrease in the value of acceleration due to gravity on the surface of the earth , if the radius of the earth decreases by 1% and the mass of the earth remains unchanged ?

Mass remaining constant , if the radius of the earth decreases by 1% what is the percentage change in acceleration due to gravity on the surface of the earth ?

If the radius of the earth decreases by 10% , the mass remaining unchanged, what will happen to the acceleration due to gravity?

If the radius of the earth decreases by 10% , the mass remaining unchanged, what will happen to the acceleration due to gravity?

If both the mass and radius of the earth decreases by 1% then the
