Question

.
If the diameter of the earth becomes twice its present value but its mass remains unchanged,
then how would the weight of an object on the surface of the earth be affected?​

Answer 1

Answer:

...

Explanation:

If diameter is doubled then radius is also doubled, i.e, the distance of the object from the center doubles. We know that weight is inversely proportional to the square of the distance, so weight reduces to one fourth its original value.
