Question 1168027
.


For your info (and for the info to other respectful tutors)



            *********************************************


                The radius of the moon is  1,079.4 miles.


            *********************************************



So,  it is a big question - - - what does it mean to be at the distance of  500   or  1000  miles from the center of the moon.



By the way,  if the body is located deeply inside of the moon,  then the statement of the problem about  "proportionality"  is 


            a)  WRONG   and   b)  INCORRECT.



My salutation to this person,  illiterate in both  Physics  and  Astronomy,  who created this post  (!)
