Q.

Match List-I with List-II.  

  List-I   List-II
A. Planck’s constant I. ML2T-2
B. Stopping potential II. T-1
C. Work function III. ML2T-1
D. Threshold frequency IV. ML2T-3A-1

 

Choose the correct answer from the options given below:                      [2026]

1 A-III, B-IV, C-I, D-II  
2 A-I, B-II, C-III, D-IV  
3 A-IV, B-III, C-I, D-II  
4 A-I, B-IV, C-III, D-II  

Ans.

(1)

(A)  [h]=[E][ν]=ML2T-2T-1=ML2T-1

(B)  Stopping potential: E=q·V0

       [V0]=[E][q]=ML2T-2AT=ML2T-3A-1

(C)  Work function (ϕ)→Energy form [ϕ]=ML2T-2

(D)  Threshold freq. [ν0]=T-1
