As we know:Gravitation is attractive force, electric force is attractive and repulsive force.

Weak and strong interaction are attractive or repulsive force?
 
Physics news on Phys.org
The repulsion/attraction of the strong interactions depends on the color charges of the particles involved, just as the repulsion/attraction of the E&M force depends on the electric charges. Similarly for the weak interactions. Gravity is the only force which is always attractive.

Thread 'Quantum behaviour of an electron around a positively charged sphere'

If we release an electron around a positively charged sphere, the initial state of electron is a linear combination of Hydrogen-like states. According to quantum mechanics, evolution of time would not change this initial state because the potential is time independent. However, classically we expect the electron to collide with the sphere. So, it seems that the quantum and classics predict different behaviours!
