हिन्दीThe dimensional formula of the ratio of Planck's constant \( h \) to Boltzmann's constant \( k_B \) is:
Correct answer · Option 1
\( [M^0 L^0 T K] \)
Explanation
Dimensions of Planck's constant \( [h] = [M L^2 T^{-1}] \) and Boltzmann's constant \( [k_B] = [M L^2 T^{-2} K^{-1}] \). Therefore, \( [\frac{h}{k_B}] = \frac{[M L^2 T^{-1}]}{[M L^2 T^{-2} K^{-1}]} = [T K] = [M^0 L^0 T K] \).
