The magntic moment `(mu)` of a revolving electron around the mucleaus

1.	The magntic moment `(mu)` of a revolving electron around the mucleaus varies with principle quantum number `n` asA. both Assertion and Reason are true and the Reason is the correct explanation of the Assertion.B. both Assertion and Reason are true but Reason is not a correct explanation of the Assertion.C. Assertion is true but the Reason is false.D. both Assertion and Reason are false.
Answer» Correct Answer - D Magnetic moment of revolving electron around the nucleus is, `M=IA=e/Tpir^2=(eomega)/(2pi)pir^2=(evr)/(2)` But `vprop1/n` and `rpropn^2` Therefore, `Mprop(e(1//n)xxn^2)/(2)` or `Mpropn` The Assertion is wrong. Here Reason though correct but cannot explain the Assertion.
