i think it is B, but alll sound so good to be true

OpenStudy (anonymous):

it's A, if you are getting near the moom, the gravitational force is given by: \[F = \frac{GMm}{r^2}\], where r is teh distance of teh spacecraft and the center of the moon. You can see that if r decreases, F increases

OpenStudy (anonymous):

were did you find that equation?

OpenStudy (anonymous):

that is gravitational law

OpenStudy (anonymous):

oh

OpenStudy (anonymous):

case is closed then, XD
