Q1:

Assertion (A): Orbital magnetic moment of an electron in an atom is of the order of 1 Bohr magneton. Reason (R): 1 Bohr magneton = 9.27 x 10-24 A/m2.

A Both A and R are true and R is correct explanation of A

B Both A and R are true but R is not correct explanation of A

C A is true but R is false

D A is false but R is true

ANS:B - Both A and R are true but R is not correct explanation of A

1 Bohr magneton = 9.27400968(20) * 10^-24 and its unit is J * T^-1.
