Answer

The weight can be calculated using the formula:

weight = mass \times gravitational \ field \ strength

Substituting the given values:

weight = 190 \ kg \times 10 \ N/kg = 1900 \ N.

Therefore, the weight of the rover on Earth is 1900 N.

Step 6

(ii) The weight of the rover on Mars is 700N. Calculate the gravitational field strength on Mars.

Answer

Using the weight on Mars, we can rearrange the formula:

weight = mass \times gravitational \ field \ strength

We need to find the gravitational field strength on Mars:

gravitational \ field \ strength = \frac{weight}{mass}

Substituting the known values:

gravitational \ field \ strength = \frac{700 \ N}{190 \ kg} \approx 3.68 \ N/kg.

Thus, the gravitational field strength on Mars is approximately 3.68 N/kg.
