Problem

Match the following Column-I with Column-II. [Assume Hydrogen like Atoms only]

Column-I		Column-II
I.	Radius of orbit is related with atomic number (Z)	P.	Is proportional to Z
II.	Current associated due to orbital motion electron with atomic number (Z)	Q.	Is inversely proportional to Z
III.	Magnetic field at centre due to orbital motion of electron related with (Z)	R.	Is proportional to $Z^2$
IV.	Velocity of an electron related with atomic number (Z)	S.	Is proportional to $Z^3$

Now choose the best match: a. I-Q; II-Q; III-S; IV-P b. I-P; II-R; III-S; IV-Q c. I-Q; II-R; III-S; IV-P d. I-Q; II-R; III-P; IV-S
