Ocer w t
1. Two students sit 1.50 mn apart. One student has a mass of 70.0 kg, and the other has
a mass of 52.0 kg. What is the gravitational force between them?
2. What is the magnitudc of the gravitational force that the moon cxerts on Earth if the centres of Earth
and the moon are 3.84x10 m apart and the moon has a mass of 7.35x10 kg ?
3. If the gravitational force between two objects of equal mass is 2.30x10 N when the objccts are
10.0 m apart, what is the mass of each object?
4. Calculate the gravitational force on a 650 kg spacecrafl that is 4.15x10 m above the
surface of Earth.
5. The gravitational force bctween two objccts that are 0.21 m apart is 3.2x10 N. If the mass of one
obicct is 55 kg, what is the mass of the other object?
6. If two objects, cach with a mass of 20x10 kg. produce a gravitational force between them of
3.7x10 N, what is the distance between them!
7. Whal is the gravitational force on a 70.0 kg object resting on Earth's surface?
8. What is the gravitat onal force on a 35.0 ke object starding on Farth's surface? (se your answer to
question 7 to reduce the calculations.)
9. What is the gravitational force on a 70 0 kp object that is 6 37x10 m above Farth's surface?
