If the mass of the Earth is decreased by 10% keeping it size constant, how is the weight of a body on the Earth affected?

If the radius of the earth is made three times, keeping the mass constant, then the weight of a body on the earth's surface will be as compared to its previous value is

If the radius of earth is reduced to 2%, keeping mass constant, then weight of the body on its surface

If the present radius of the earth is doubled keeping the mass unchanged, how will the weight of a body on the surface of the earth change ?

If radius of the earth contracts 2% and its mass remains the same, then weight of the body at the earth surface

If the Earth shrinks to 50% of its real redius its mass remaining the same , the weight of a body on the Earth will ___________

The weight of a body on the earth's surface is W. if the radius of the earth becomes double keeping its mass unchanged, what will be the weight of the body ?
