2. What is the gravitational constant (G) value approximately in N(m/kg)^2?

3. If the distance between two masses is doubled, how does the gravitational force between them change?

4. Which factor does NOT directly affect the gravitational force between two objects?

5. What must be true for an object to be in geosynchronous orbit around Earth?

6. In the context of gravitational force, what does it mean if two objects are inversely proportional to the square of the distance between them?

7. Which is a possible consequence of the Earth's gravitational pull on the Moon?

8. Calculate the gravitational force between two objects if their masses are 10 kg and 20 kg respectively, and they are separated by a distance of 2 meters. Use the gravitational constant $G = 6.674 \times 10^{-11} N(m/kg)^2$.
