Q.

Match List I with List II

  List I   List II
A. Young's Modulus (Y) I. [ML1T1]
B. Co-efficient of Viscosity (η) II. [ML2T1]
C. Planck's Constant (h) III. [ML1T2]
D. Work Function (ϕ) IV. [ML2T2]

Choose the correct answer from the options given below:          [2023]

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

Ans.

(4)

Y=StressStrain=F/Al/l=[MLT2][L2]=[ML1T2]

F=6πηrv  η=F6πrv

[η]=[MLT2][L][LT1]=[ML1T1]

E=hv  h=Ev=[ML2T2][T1]=[ML2T1]

Work function has same dimension as that of energy, so

[ϕ]=[ML2T2]
