Calculate the gravitational force between the Earth and the Sun.

(a) Calculate the distance from the Earth's surface of the point which the gravitational field strength is zero, given the following data: Distance between the Earth and the Moon = 384 000 km; Mass of the Earth = 5.98 x 10^24 kg; Mass of the Moon = 7.35 x 10^22 kg; Radius of the Earth = 6.37 x 10^6 m (b) If a small mass is placed at this point, does is receive gravity force? Is the gravitational potential energy at this point equal to 0? Explain your answer.

The International Space Station has a mass of 4.19 ✕ 105 kg and orbits at a radius of 6.79 ✕ 106 m from the center of Earth. Find the gravitational force exerted by Earth on the space station, the space station's gravitational potential energy, and the weight of an 88.3 kg astronaut living inside the station. Just need the answer to option B   (a) the gravitational force (in N) exerted by Earth on the space station (Enter the magnitude.)   3622431.86 N (b) the space station's gravitational potential energy (in J)   _____________J (c) the weight (in N) of an 88.3 kg astronaut living inside the station  763.39 N

Two objects attract each other with a gravitational force of magnitude 1.01 If the total mass of the two objects is 5.12 kg, what is the mass of each? 10^-8 N when separated by 19.4 cm. heavier mass: kg lighter mass : kg
