Assertion (A): The angular momentum of an atom is due to three contributions viz. orbital, electron spin and nuclear spin. Reason (R): The nuclear spin magnetic moment is much more than electron spin magnetic moment.
Assertion (A): Resistivity of a perfect single crystal of a metal goes to zero as T approaches zero. Reason (R): Scattering of electrons is due to deviations from perfect periodicity of lattice.
Assertion (A): Holes are majority carriers in p type semiconductor. Reason (R): In p type semiconductor, the electrons produced by thermal agitation recombine with holes.
