When an electrons revolves around the nucleus so how centripetal force is provided by electrostatic force of attraction

Dear Anubhav Sharma,

The Electrons repel each other and with the electrons ni the lower orbitals in the atom . Now the repulsive force between the electrons and the attractive force between the Electrons and the Nucleus provide the centripetal force for the electron to revolve around the nucleus.

Hope this helped you immensely..!

All the Very Best & Good Luck to you ..!!

F=q1q2/r^2. This is the electrostatic force. Just like in the case of earth and sun, gravitational force proved centripretal force, the attraction b/w electrons and protosns (being electrostatic ) provides the centripretal force here
