Question

3. How much does the force of gravity change between the earth and a receding rocket when the distance between them is doubled?

Answer 1

Answer:

hope it is helpful

Explanation:

Let the mass of the two bodies be M1&M2

Let the distance between them is R

∴F=R2GM1M2

If R=r/2

then F1=R2/4GM1M2=R24GM1M2=4F

Thus if the distance between the 2 bodies is reduced to half, the force of gravitation is quadrupled.
