Question

what is the dimension of work function​

Answer 1

Answer:

Derivations from other quantities :  W = F ⋅ s W = τ θ

Dimension of work:  M L2 T−2

Explanation:

The SI unit of work is the joule (J), the same unit as for energy.

Work function has the same dimensions as energy i.e  [ML2T−2]  

Since work function is defined as the minimum energy required to remove the electron from an atom. Therefore it is given by

Φ=hν0  

Where  h=6.625×10−34Js  is a plank’s constant which is having the unit joules-second. Therefore its dimensions are  [ML2T−1]  

ν0  is the threshold frequency. Frequency is defined as the reciprocal of time. so its dimension is  [T−1] .

Therefore the dimension of work function is given by

Φ=[M1L2T−1][T−1]=[M1L2T−2]

Answer 2

Answer: Dimension of work function is $\bold{M L^2 T^{-2}}$.

Explanation:

The SI unit of work is the joule (J), the same unit as for energy.

Work function has the same dimensions as energy i.e  [ML2T−2]  

Since work function is defined as the minimum energy required to remove the electron from an atom. Therefore it is given by

$\phi =h\upsilon _o$  

Where  h=6.625×10−34Js  is a plank’s constant which is having the unit joules-second. Therefore its dimensions are $[ML^{2}T^{-1}]$

$\upsilon _o$ is the threshold frequency. Frequency is defined as the reciprocal of time. so its dimension is $[T^{-1}]$.

Therefore the dimension of work function is given by

$\phi =[M^1L^2T^{-1}][T^{-1}]=[M^{1}L^{2}T^{-2}]$

Hence, the dimension of work function is $[\phi] =[M^{1}L^{2}T^{-2}]$.
