AIIMS 2018 Physics Bohr's Model Assertion Reason Question
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.
If both assertion and reason are true and reason is the correct explanation of assertion.
If both assertion and reason are true but reason is not the correct explanation of assertion.
If assertion is true but reason is false.
If both assertion and reason are false.
Correct Answer
Detailed Explanation
In Bohr's atomic model, electrons occupy fixed orbits around the nucleus, characterized by specific energy levels. While in these stable orbits, electrons do not emit energy in the form of electromagnetic radiation, which is a key postulate of the model. This stability allows for quantized energy states, meaning electrons can only exist in certain defined energy levels, transitioning between them by absorbing or emitting energy when moving to different orbits. The other options, being unspecified, do not provide any relevant information or alternative explanations related to the principles of Bohr's model.
