An astronaut takes his bathroom scale to the moon and then stands on it. Is the reading of the scale his true weight? Select the correct explanation. An astronaut takes his bathroom scale to the moon and then stands on it. Is the reading of the scale his true weight? Select the correct explanation:

A. The reading on the moon will be the moon-weight, or the friction force of the moon surface on the astronaut. This would be equal to the astronaut's earth-weight or the friction force of the earth's surface on the astronaut (while standing on the scales on the earth).

B. The reading on the moon will be the moon-weight, or the gravitational force of the moon on the astronaut. This would be about 1/6 of the astronaut's earth-weight or the gravitational force of the earth on the astronaut (while standing on the scales on the earth).

C. The reading on the moon will be the moon-weight, or the gravitational force of the moon on the astronaut. This would be about 6 times of the astronaut's earth-weight or the gravitational force of the earth on the astronaut (while standing on the scales on the earth).

D. The reading on the moon will be the moon-weight, or the gravitational force of the moon on the astronaut. This would be equal to the astronaut's earth-weight or the gravitational force of the earth on the astronaut (while standing on the scales on the earth).
