## Homework Equations

Centripetal acceleration Mv^2/r

## The Attempt at a Solution

I guess the answer to be D

But I am not quite sure about the same rate of acceleration.

If we hypothetically remove the space station and visualize the astronaut orbiting around the Earth alone (in his spacesuit), again according to Newton's law of gravitation he must feel weightlessness (wouldn't he ? ). This would happen when his entire weight is providing the Centripetal Force required for acceleration at a particular velocity .

So does this explanation not render choice D as

**incorrect**? So the next correct choice looks "A" but again it is flawed since Earth's gravitational field is theoretically infinite .
