if electrons has -ve charge and protons have +ve charge then why they donot collide with each other

We know that in an atom, the nucleus is the positively charged body which is present at the centre of the atom, with electrons orbiting the nucleus in orbits. As the nucleus is positively charged and the electron is negatively charged there would be force of attraction between the electron and the nucleus. However, this force of attraction between the nucleus and the electron is balanced by the centrifugal force of the revolving electron. Centrifugal force is the fictitious outward force experienced by body in circular path.
Had the electron been stationary, then it would have collapsed into the nucleus. But this doesn't happen as the electron is not stationary and is revolving around the nucleus. Thus the attractive forces and the centrifugal force compensate each other and hence the electron does not fall in the nucleus. Also, another important point to note is that an electron does not lose or gain energy as long as it is moving in the same orbit.
