If the distance between two masses each 1kg, is 1m, then the force of attraction between the two will be:
Correct answer: B. 6.67 x 10^-11 N
- A. 9 x 10^9 N
- B. 6.67 x 10^-11 N
- C. 3 x 10^-11N
- D. 8.8 x 10^-12 N
Explanation
F=GMm/R2 As the distance and both the masses are equal to 1, F= G Where G is a universal gravitational constant with the value of 6.67 x 10-11 N .

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.
