Assertion: Electrons in the atom are held due to coulomb forces.
Reason: The atom is stable only because the centripetal force due to Coulomb's law is balanced by the centrifugal force.

Electron in the atom are held due to

(A) Electrons in the atom are held due to coulomb forces (R) : The atom is stable only because the centripetal force due to coulomb's law is balanced by the centrifugal force

A: Electric force is the reason for electron to remain in a atom. R : According to Coulomb's law, the electron in a atom can remain stable in nucleus only if the centripetal force is equal to its centrifugal force.

Explain centrifugal force due to rotation of the earth
