If the radius of the earth becomes half of its present value (mass remaining the same ), the new length of the day would be

If the radius of the earth becomes half of its present value but its density remains unchanged then find the weight of body on the surface of earth.

If the radius of the earth contracts to half of its present radius , then the length of the day will be (if the mass of the earth remaining same)

If the radius of the earth was half of its present value and its mass (1//8)^("th") of the present mass, the g value would have been reduced to

If the radius of the earth suddenly decreases to 80% of its present value, the mass of the earth remaining the same, the value of the acceleration due to gravity will

If the radius of the earth suddenly decreases to 80% of its present value, the mass of the earth remaining the same, the value of the acceleration due to gravity will

How does the weight of an object vary with respect to mass and radius of the earth. In a hypothetical case, if the diameter of the earth becomes half of its present value and its ,mass becomes four times of its present value, then how would the weight of any object on the surface of the earth be affected?
