The correct Answer is:
To solve the problem of the two astronauts floating in gravitational free space, we need to analyze the forces acting on them due to their masses. ### Step-by-Step Solution: 1. **Understanding the Scenario**: - Two astronauts are floating in space, meaning they are in a microgravity environment where the effects of large gravitational bodies are negligible. - They have lost contact with their spaceship, so they are not being influenced by any external forces. 2. **Identifying the Masses**: - Let the masses of the two astronauts be \( m_1 \) and \( m_2 \). 3. **Gravitational Attraction**: - According to Newton's law of universal gravitation, any two masses exert a gravitational force on each other. The force \( F_g \) between the two astronauts can be calculated using the formula: \[ F_g = \frac{G \cdot m_1 \cdot m_2}{r^2} \] - Here, \( G \) is the gravitational constant, and \( r \) is the distance between the two astronauts. 4. **Direction of the Force**: - The gravitational force acts as an attractive force. This means that astronaut 1 will experience a force pulling them towards astronaut 2, and astronaut 2 will experience a force pulling them towards astronaut 1. 5. **Resulting Motion**: - Since both astronauts experience equal and opposite gravitational forces, they will begin to move towards each other due to this mutual attraction. 6. **Conclusion**: - Therefore, the correct answer is that the two astronauts will move towards each other. ### Final Answer: The two astronauts will move towards each other (Option 2).
