An astronaut is travelling in a space station that is moving in orbit above the Earth. Within the space station, the acceleration due to gravity is $7.5\,\text{m s}^{-2}$. At the Earth’s surface, the acceleration due to gravity is $10\,\text{m s}^{-2}$. Which statement about the astronaut’s mass and weight in the space station is correct?
- 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
