Question 1

Match List I with List II
List I   List II
A. Young's Modulus (Y)        I. [ML$$^{-1}$$T$$^{-1}$$]
B. Co-efficient of Viscosity ($$\eta$$)   II. [ML$$^2$$T$$^{-1}$$]
C. Planck's Constant (h) III. [ML$$^{-1}$$T$$^{-2}$$]
D. Work Function ($$\phi$$)     IV. [ML$$^2$$T$$^{-2}$$]

Matching physical quantities with their dimensional formulae:

A. Young's Modulus (Y): Stress/Strain = (Force/Area) = [MLT⁻²]/[L²] = [ML⁻¹T⁻²] → III

B. Coefficient of Viscosity (η): [ML⁻¹T⁻¹] → I

C. Planck's Constant (h): E = hν → h = E/ν = [ML²T⁻²]/[T⁻¹] = [ML²T⁻¹] → II

D. Work Function (φ): Energy = [ML²T⁻²] → IV

Matching: A-III, B-I, C-II, D-IV

The correct answer is Option 2.
