Mass and weight — practice question

A spacecraft transports a probe to Mars, where the gravitational field strength is $3.7\,\text{N kg}^{-1}$. On Mars, the probe has a weight of $370\,\text{N}$. On Earth, the gravitational field strength is $9.8\,\text{N kg}^{-1}$. What are the mass and the weight of the probe on Earth?

  • Amass $100\,\text{kg}$, weight $370\,\text{N}$
  • Bmass $100\,\text{kg}$, weight $980\,\text{N}$
  • Cmass $370\,\text{kg}$, weight $98\,\text{N}$
  • Dmass $370\,\text{kg}$, weight $3700\,\text{N}$
