Answer
To calculate the weight of the rover, we use the formula:
weight=mass×gravitationalfieldstrength
Substituting in the values:
weight=190kg×10N/kg=1900N
So, the weight of the rover on Earth is 1900 N.
Step 6

Answer
We know the weight of the rover on Mars is 700 N. We can rearrange the weight formula to find the gravitational field strength:
gravitationalfieldstrength=massweight
Substituting the values:
gravitationalfieldstrength=190kg700N≈3.68N/kg
Thus, the gravitational field strength on Mars is approximately 3.68 N/kg.
