Question

Consider Bohr's model to be valid for a hydrogen like atom with atomic number Z. Match quantities given in Column -I to those given in Column II.

Column I		Column II
A	Magnetic field is proportional to	1	$Z ^2 / n ^3$
B	Angular speed is proportional to	2	$Z ^3 / n ^5$
C	Time period is proportional to	3	$n$
D	Angular momentum is proportional to	4	$n ^3 / Z ^2$

• A. $(A) \rightarrow (2); (B) \rightarrow (1); (C) \rightarrow (4); (D) \rightarrow (3)$
• B. $(A) \rightarrow (1); (B) \rightarrow (2); (C) \rightarrow (1); (D) \rightarrow (4)$
• C. $(A) \rightarrow (3); (B) \rightarrow (2); (C) \rightarrow (1); (D) \rightarrow (4)$
• D. None of these

Answer 1

Answer: (A)

(A) $\rightarrow(2) ;( B ) \rightarrow(1) ;( C ) \rightarrow(4) ;( D ) \rightarrow(3)$
