experimentx · Answer

gravitational force is always attractive

anonymous · Answer

option A.  It is always attractive

anonymous · Answer

is it always repulsive too check the question its says NOT

anonymous · Answer

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

anonymous · Answer

So Gravitational force is always attractive in nature
