Question

A woman whose mass is 60 kg on the Earth's surface is in a spacecraft at a height of 2 Earth radii above the Earth's surface. Her mass there is:?

Answer 1

The woman's mass remains 60 kg regardless of her location, even in a spacecraft at a height of 2 Earth radii above the Earth's surface, since mass is a property of matter that does not change.

Step-by-step explanation:

The woman's mass on the Earth's surface is 60 kg. Mass is an intrinsic property of matter and does not change regardless of location. Therefore, even when she is in a spacecraft at a height of 2 Earth radii above the Earth's surface, her mass remains the same, 60 kg. It is only her weight, which is the force of gravitational attraction, that would change due to the increased distance from the Earth's center. The decrease in the force of gravity can be calculated using Newton's law of universal gravitation, which takes into account the mass of the Earth and the distance from the center of the Earth.
