A portable battery unit weighs 250 N on the Earth, where g=10 N/kgg=10\ \mathrm{N/kg}g=10 N/kg. The battery unit is taken to Mars, where g=3.7 N/kgg=3.7\ \mathrm{N/kg}g=3.7 N/kg.
Four students calculate the weight of the battery unit on Mars.
| Student | Calculated weight |
|---|---|
| Adam | 25 N |
| Beth | 67.6 N |
| Evan | 92.5 N |
| Maya | 925 N |
Which student is correct?
Beth
Adam
Maya
Evan
