Vedclass · Answer

(A) According to classical electromagnetic theory,an accelerated charged particle must emit electromagnetic radiation. Since an electron revolving in an orbit is undergoing centripetal acceleration,it should continuously lose energy and spiral into the nucleus,making the atom unstable. To resolve this,Bohr postulated that electrons revolve in specific 'stationary' orbits where they do not radiate energy. Thus,the Assertion is correct because Bohr had to make this assumption to explain atomic stability,and the Reason is correct because it describes the classical conflict that necessitated Bohr's postulate. Therefore,the Reason correctly explains 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.
