C{'text': 'Keeps the Moon in orbit around Earth', 'label': 'C'}
D{'text': "Only tides, not Moon's motion", 'label': 'D'}
Answer & Solution
Correct answer: A. {'text': 'Both A and B', 'label': 'A'}
1. Newton's law of gravitation unified terrestrial and celestial mechanics.
2. The same 1/r² attractive law explains falling objects on Earth.
3. It also holds the Moon in its orbit around Earth.
4. Ocean tides are also caused by the Moon's and Sun's gravitational pulls.
