Question. The gravitational field strength of Jupiter is $22.9 \, \text{N/kg}$. An astronaut weighs 1200 N on Earth. What will his weight on Jupiter be?

Solution. Noting that the gravitational field strength of Earth is $9.8 \, \text{N/kg}$ we find the mass of astronaut: $m = \frac{P_E}{g_E} = \frac{1200}{9.8} \approx 122.45 \, \text{kg}$. Then we find his weight on Jupiter:

$$P_J = m g_J = 122.45 \cdot 22.9 \approx 2804 \, \text{N}.$$

Answer. 2804 N.
