## woleraymond 3 years ago Which of these is NOT a statement of Newton’s law of universal gravitation? a. gravitational force between two particles is attractive as well as repulsive b gravitational force acts along the line joining the two particles c. gravitational force is directly proportional to the product of the masses of the particles d. gravitational force is inversely proportional to the square of the distance of the particles apart

1. experimentX

gravitational force is always attractive

2. shivam_bhalla

option A. It is always attractive

3. woleraymond

is it always repulsive too check the question its says NOT

4. shivam_bhalla

Well The equation is $F = {{G m_1*m_2}\over{r^2}}$ Now tell me which quantity can be negative? Answer-->none

5. shivam_bhalla

So Gravitational force is always attractive in nature

6. experimentX

conclusion: A must be false.

7. Prof.Grace

that's right: conclusion is A is false

8. woleraymond

@Prof.Grace which school are u from?

9. Prof.Grace
