Vedclass · Answer

(B) According to classical physics,any charged particle undergoing acceleration must radiate electromagnetic energy. Since an electron revolving in an orbit around the nucleus is undergoing centripetal acceleration,classical electrodynamics predicts it should continuously lose energy and spiral into the nucleus. To resolve this instability,Bohr postulated that electrons in specific 'stationary' orbits do not radiate energy. Both the Assertion and the Reason are scientifically correct statements. However,the Reason describes the classical conflict,while the Assertion describes Bohr's specific quantum postulate to overcome that conflict. The Reason does not explain *why* Bohr's postulate is true; it only explains why the postulate was *necessary*. Therefore,the Reason is not the correct explanation of the Assertion.

Assertion : Bohr had to postulate that the electrons in stationary orbits around the nucleus do not radiate.
Reason : According to classical physics all moving electrons radiate.
