Answer 2

$\Large{\underline{\underline{\bf{Question :}}}}$

Write the Dimension formula of planck's constant ?

__________________________

$\Large{\underline{\underline{\bf{Solution :}}}}$

We know that,

$\Large{\implies{\boxed{\boxed{\sf{E = hv}}}}}$

$\sf{→ h = \frac{E}{v}}$

We know dimension formula of enery ($\sf{M^1 L^2 T^{-2})}$ and velocity ($\sf{T^{-1})}$

$\sf{→ h = \frac{M^1 L^2 T^{-2}}{T^{-1}}} \\ \\ \sf{→h = M^1 L^2 T^{-1}} \\ \\ \Large{\implies{\boxed{\boxed{\sf{h = M^1 L^2 T^{-1}}}}}}$
