Inside a satellite orbiting very close to the earth's surface, water does not fall out of a glass when it is inverted. Which of the following is the best explanation for this ?

Answer»

The earth does not EXERT any force on the water
The earth's force of a attraction on the water is EXACTLY balanced by the force CREATED by the satellite's motion
The water and the GLASS have the same acceleration, equal to g, towards the same of the earth, and hence there is no relative motion between them
The gravitational attraction between the glass and the water balanced the earth's attraciton on the water.
