Question

On which planet would you weigh more if you traveled to two different planets that were the exactly the same size but one was made completely of iron and the other swiss cheese

Answer 1

The weight of an object is known to occur from the gravitational pull of the earth. Hence, for weight to occur, a certain force should be there. The more the gravitational pull the more the force.

According to this information, the planet made of iron will have high gravitational pull. Hence, the weight of an organism will be more on a planet made of iron rather than a planet made of cheese.
