An object aboard a space probe above the Earth has a weight of $3.5\,\text{N}$. At the probe’s altitude, the gravitational field strength is $7.0\,\text{N kg}^{-1}$. On the Earth’s surface, the gravitational field strength is $10\,\text{N kg}^{-1}$. What are the object’s mass and its weight at the Earth’s surface?
- A$0.50\,\text{kg}$ and $3.5\,\text{N}$
- B$0.50\,\text{kg}$ and $5.0\,\text{N}$
- C$2.0\,\text{kg}$ and $3.5\,\text{N}$
- D$2.0\,\text{kg}$ and $20\,\text{N}$
