Forces — practice question

A space probe records the gravitational field strength at four separate distances from a planet. It takes the reading at the greatest distance from the planet first and the reading at the smallest distance from the planet last. In what sequence were the measurements made?

  • A$6.3\,\text{N/kg},\ 10\,\text{N/kg},\ 14\,\text{N/kg},\ 20\,\text{N/kg}$
  • B$10\,\text{N/kg},\ 14\,\text{N/kg},\ 6.3\,\text{N/kg},\ 20\,\text{N/kg}$
  • C$20\,\text{N/kg},\ 14\,\text{N/kg},\ 6.3\,\text{N/kg},\ 10\,\text{N/kg}$
  • D$20\,\text{N/kg},\ 14\,\text{N/kg},\ 10\,\text{N/kg},\ 6.3\,\text{N/kg}$
