The graph illustrates the way weight changes with mass on planet P and on planet Q. An object has a weight of $400\,\text{N}$ on planet P. The object is then moved to planet Q. Which row is correct?
- Amass of object on planet Q $= 40\,\text{kg}$, weight of object on planet Q $= 200\,\text{N}$
- Bmass of object on planet Q $= 40\,\text{kg}$, weight of object on planet Q $= 400\,\text{N}$
- Cmass of object on planet Q $= 80\,\text{kg}$, weight of object on planet Q $= 200\,\text{N}$
- Dmass of object on planet Q $= 80\,\text{kg}$, weight of object on planet Q $= 400\,\text{N}$
