We all know that all the forces in nature exist in opposites, but gravitational force is the only force that always attracts every object and never reples any.
Why gravitational force is attractive?
Let’s look at the formulas of gravitational force and electric charge:
Both the formulas seem to be similar but the electric charge force reples the charges if they are oppositely charged, but gravitational force attracts equally charged particles too. So it can be assumed that all the particles existing on the earth are so negativiely charged when compared to gravitation force that, these particles are always attracted by the gravity.
