$[$Q$5]$ A small asteroid creates a gravitational force of $360$ N on a nearby spacecraft when they are separated by a distanca of $10$ km $.$ If the distance between the two is decreased to $5$ km and the spacecraft is not re$-$fueled so its mass remains the same, what happens to the gravitational force between the asteroid and the spacecraft?

a$.$ It would be four times as large.

b$.$ It would be twice as large.

c$.$ It would be the same.

d$.$ It would be hali as large.

e$.$ It would be one forth as large.
