The gravitational attraction between two particles acts along which line?
AA line crossing them
BA line dividing them
CA line joining them
DA line beneath them
Answer & Solution
Correct answer: C. A line joining them
1. Gravitation is a force between two particles, not a field effect at a distance.
2. Its direction is fixed by the positions of the two particles alone.
3. Every particle attracts every other with a force along a line joining them.
4. So the answer is a line joining them.
