A space station is travelling in orbit above Earth, and an astronaut is inside it. Inside the space station, the acceleration of free fall is $7.5\,\text{m s}^{-2}$. On Earth, the acceleration of free fall is $9.8\,\text{m s}^{-2}$. Which row gives the correct values for the astronaut’s mass and weight in the space station?
- Amass of astronaut: same as on the Earth; weight of astronaut: less than on the Earth
- Bmass of astronaut: same as on the Earth; weight of astronaut: greater than on the Earth
- Cmass of astronaut: lower than on the Earth; weight of astronaut: less than on the Earth
- Dmass of astronaut: lower than on the Earth; weight of astronaut: greater than on the Earth
