The force of attraction acts along the:
Correct answer: B. Line joining the interacting bodies
- A. Axis of rotation
- B. Line joining the interacting bodies
- C. Line perpendicular to the interacting bodies
- D. None of these
Explanation
The force of attraction is always along the line joining the interacting bodies, be it imaginary or real. Hence C is correct .

About Gravitation
Newton’s law of universal gravitation relates the force between masses to their masses and separation, while gravitational field strength explains weight and orbital motion. The topic covers satellite velocity and period, escape ideas, weightlessness in free fall, and artificial gravity, which differs from ordinary gravitational attraction.
