Solution

The correct option is B $V_{A} > V_{B}, Z_{A} < Z_{B}$
$λ_{m i n}$ of A < $λ_{m i n}$ of B
$∴ V_{A} > V_{B}; λ_{k_{α B}} < λ_{k_{α A}}$
$∴ Z_{B} > Z_{A}$
So, the answer is option (B).

Q. The figure shows the intensity-wavelength relations of X-rays coming from two different Coolidge tubes. The solid curve represents the relation for the tube A in which the potential difference between the target and the filament is V_A and the atomic number of the target material is Z_A. These quantities are V_B and Z_B for the other tube. Then,
(a) V_A > V_B, Z_A > Z_B
(b) V_A > V_B, Z_A < Z_B
(c) V_A < V_B, Z_A > Z_B
(d) V_A > V_B, Z_A < Z_B
