You and your friends are having a discussion about weight. He/she claims that he/she weighs less on the 100th floor of a building than he/she does on the ground floor. Is he/she correct?

Yes she is correct

Explanation:

The friend is correct.

Weight is the product of mass and acceleration due to gravity of an object.

       Weight  = mass x acceleration due to gravity

The acceleration due to gravity of a body is the pull of the earth on any body on the surface. It is an attractive fore between two bodies with mass. The farther a body is from the earth surface the lesser the force of gravity.

Mass is the amount of matter in a substance. It does not vary.

Therefore, since acceleration due to gravity reduces as we move from the earth surface, her weight will reduce.
