To find the distance from the Earth's center where the gravitational force on the rocket is zero, we can follow these steps: ### Step-by-Step Solution: 1. **Identify the Variables**: - Let \( M_1 \) be the mass of the Sun: \( M_1 = 2 \times 10^{30} \, \text{kg} \) - Let \( M_2 \) be the mass of the Earth: \( M_2 = 6 \times 10^{24} \, \text{kg} \) - Let \( R \) be the distance from the Earth to the Sun: \( R = 1.5 \times 10^{11} \, \text{m} \) ...
