When a spacecraft travels away from earth, the gravitational force acting on it

increases

decreases

increases first and then decreases

decreases first and then increases

Gravitational force on aircraft at some distance from the Earth is given as

here we know that

= mass of Earth

= mass of aircraft

r = distance between center of earth and aircraft

now as the aircraft is flying away from the surface of Earth so here the distance between them is increasing with the motion of aircraft

So as it moves away the force between them will decrease

So here we can say that

When a spacecraft travels away from Earth, the gravitational force acting on it  

decreases

in order to follow the instructions and complete the statements, i need to use data from table c of your student guide. can you think of a way to let me see your student guide for a while ? i can't answer the question without the data in table c.
