Question

Some physical constants are given in List 1 and their dimensional formulae are given in List 2.Match the correct pairs in the lists:

• A. (1) D, (2) C, (3) B, (4) A
• B. (1) B, (2) A, (3) C, (4) D
• C. (1) C, (2) B, (3) A, (4) D
• D. (1) C, (2) D, (3) A, (4) B

Answer 1

Answer: (D)

(1) C, (2) D, (3) A, (4) B

Answer 2

Dimensions of Plancks constant $=[M{{L}^{2}}{{T}^{-1}}]$ Dimensions of gravitational constant $=[{{M}^{-1}}{{L}^{3}}{{T}^{-2}}]$ Dimensions of bulk modulus $=[M{{L}^{-1}}{{T}^{-2}}]$ Dimensions of coefficients of viscosity $=[M{{L}^{-1}}{{T}^{-1}}]$ Hence, option is true.
