A  satellite  is  in  orbit  around  the  earth.  If  an  additional  module  is  attached  to  the  satellite  that  triples  its  mass,  what  happens  to  the  gravitational  force  that  it  experiences?

The  space  shuttle  is  working  on  a  weather  satellite  at  an  orbit  of  20,000m  from  the  center  of  the  earth.  If  it  then  increases  its  orbit  to  40,000m  in  order  to  work  on  a  GPS  satellite,  what  happens  to  the  gravitational  force?

The  space  shuttle  is  working  on  a  weather  satellite  at  an  orbit  of  20,000m  from  the  center  of  the  earth.  If  it  then  increases  its  orbit  to  100,000m  in  order  to  work  on  a  GPS  satellite,  what  happens  to  the  gravitational  force?

An  alien  spaceship  orbiting  around  Earth  at  a  height  of  100,000m  experiences  a  force  from  gravity  of  25N.  After  lowering  its  orbit,  the  ship  experiences  a  gravitational  force  of  100N.  How  high  is  its  orbit  now?

An  alien  spaceship  orbiting  around  Earth  at  a  height  of  30,000m  experiences  a  force  from  gravity  of  10N.  After  lowering  its  orbit,  the  ship  experiences  a  gravitational  force  of  90N.  How  high  is  its  orbit  now?
