An astronaut is doing a spacewalk on a long tether at 0.05 km away from an orbiting satellite. His spacesuit includes a very sensitive gravitometer, which indicates the gravitational force acting on the astronaut and his spacesuit from the satellite is 3.34 Eā8 N. If the mass of the astronaut and his suit is 250 kg, what is the mass of the satellite if G = 6.67 Eā11 N*m2/kg2? (1 point)
4,000 kg
5,000 kg
6,000 kg
7,000 kg
An astronaut on the ISS is doing an experiment with two puffy Cheetos inside a carefully sealed container. A charge of 1.2 Eā5 C is place on the first Cheeto. The second one receives a charge of 2.5 Eā6 C. The force acting on the first Cheeto is 5.73 Eā1 N. What is the distance between the Cheetos if k = 8.99 E9 N*m2/C2? (1 point)
40 cm
49 cm
60 cm
70 cm
At its closest distance from Earth, the moon experiences a gravitational force of 2.22 E 20 N. The mass of the Earth is 5.97 E24 kg. The mass of the moon is 7.35 E22 kg. What is the distance between the Earth and the moon at that point if G = 6.67 Eā11 N*m2/kg2? (1 point)
1.32 E 4 km
3.63 E 6 km
3.63 E 8 km
1.32 E 17 km
