Question

Q.21 Derive the expression for the energy of an electron in the atom.
​

Answer 1

Answer:

Consider a hydrogen like atom having only one electron. ... The force acting on the electron will be given by Coulomb's Law. F=(Ze)(−e)4πε0r=−Ze24πε0r. Since it is a circular motion, this force will be the force required to keep the electron in circular motion and hence will be equal to the centripetal force.
