If uncertainty in position and momentum are equal, then uncertainty in velocity is

Consider the following sets of quantum numbers :

	n		l		m		s
(i)	3		0		0		+1/2
(ii)	2		2		1		+1/2
(iii)	4		3		-2		-1/2
(iv)	1		0		-1		-1/2
(v)	3		2		3		+1/2

Which of the following sets of quantum number is not possible ?

The orientation of an atomic orbital is governed by

Given : The mass of electron is 9.11 $$ \times $$ 10^$$-$$31 kg, Planck constant is 6.626 $$ \times $$ 10^$$-$$34 J s, the uncertainty involved in the measurement of velocity within a distance of 0.1 $$\mathop A\limits^ \circ $$ is
